Sigma BF Evaluation | PCMag


Sigma turned nearly each head within the photograph trade with its “radically easy” BF mirrorless digital camera ($1,999, physique solely). The total-frame L-mount mirrorless mixes stylish, ultra-modern design with a simplified interface that is supposed to place as few obstacles and distractions in your manner as attainable so you may think about the basics of images, like composition, publicity, and shade. This comes at a value: The BF cuts out lots of the options we have come to take with no consideration and suffers from an underpowered battery that will not get you thru the day. Even so, the BF would not fake to compete with mainstream, do-everything cameras just like the Nikon Z6III ($2,499.95, physique solely), our full-frame Editors’ Selection winner. It is an intriguing, completely beautiful different for creators who wish to tread off the crushed path.


Design: Unibody Aluminum in Silver or Black

The BF is as a lot an industrial design showcase as it’s a photographic instrument. The place most cameras are constructed up round an inner chassis (sometimes magnesium alloy), Sigma as a substitute opts for aluminum supplies and a unibody construct. Every BF digital camera is milled out of a strong block of aluminum, a fabrication approach that is confirmed to ship equally gorgeous, futuristic-looking tech merchandise up to now. The discontinued Leica T collection involves thoughts instantly, in addition to MacBook Professional laptops, which have used unibody building for years.

Since 1982, PCMag has examined and rated 1000’s of merchandise that can assist you make higher shopping for selections. See how we take a look at.

The aluminum supplies and manufacturing methodology come collectively for a putting digital camera, one which feels prefer it got here out of a classy European design home greater than a stalwart of the Japanese digital camera trade. Its model may come on the expense of sturdiness: I observed the black model loaned to me for overview misplaced a few of its sheen after a few weeks of day by day use, selecting up items of mud and displaying fingerprint marks on its exterior, and I’m weary of how the aluminum will maintain as much as dings and dents through the years. The BF is prone to require some common cleansing and cautious use to maintain it wanting new. As for capturing outside, Sigma says the BF contains mud and splash safety however cautions that it is solely adequate for use in mild rain. This is not a digital camera that you’re going to wish to take out in a downpour or blizzard.

Even so, if any digital camera model goes to attempt one thing so daring, Sigma is the candidate. Within the digital period, it is earned a status for quirky, off-kilter physique design and Foveon imaging tech. There are many examples, but when there’s one to level out, it is the dp Quattro compact collection, which put the unusual three-layer imaging tech into an extra-wide physique with a hard and fast prime lens and an odd, backward-angled grip. Sigma hasn’t but made a full-frame Foveon chip; it is engaged on one however has confronted technical challenges bringing it to market. Due to this, the BF makes use of a regular BSI CMOS chip with a Bayer sample shade filter array.

The BF skips the handgrip altogether. Its 2.9-by-5.1-by-1.4-inch (HWD), 15.7-ounce body has a flat entrance, a alternative that signifies that it is best paired with a small, mild prime lens. The physique contains diamond knurling on the appropriate facet of the entrance and a sculpted thumb relaxation on the rear, and collectively, they supply sufficient of a grip so the digital camera is not liable to slide out of your hand. The BF match comfortably in my hand when holding it in entrance of my face to take a picture, however I struggled to discover a safe, comfy technique to maintain it when strolling round city between photograph ops. I had to make use of the digital camera for a number of days and not using a wrist strap and located that gripping it by the rear plate, with my fingers excessive and thumb cradling the underside, was the perfect resolution.

Flat-front cameras are nothing new; there are many previous movie cameras on this model, plus latest digital choices just like the Panasonic Lumix S9, the Sigma fp, and luxurious entries from Leica, together with the Q3 and M11-P. However with any of these, you should buy an official add-on grip if you would like, whereas Sigma doesn’t supply one for the BF. We’ll have to attend and see if third events will step in to fill the hole.

Nonetheless, it is a good suggestion to make use of a strap for some additional peace of thoughts. The BF would not embrace one, so you may select your personal. Your choices are considerably restricted, nonetheless, because the BF solely has a single strap lug on its proper facet and a regular tripod socket on the underside. This narrows choices to both a wrist strap or a strap that secures through the tripod socket.

I paired the digital camera with the Peak Design Cuff wrist strap and located it to be a workable resolution, however I missed with the ability to let go and easily have the digital camera dangle at my facet. I’ve not tried it personally, however including a C-Loop accent to the tripod socket will allow you to use a regular strap with twin mounting factors for cross-body, shoulder, or neck carry. I additionally thought of attempting the BF with a Blackrapid Curve, a heavy-duty strap that secures through the tripod socket, however the Curve is outsized and utilitarian to the purpose that it clashes with the BF’s model.

The BF is an interchangeable lens digital camera and works with L-mount lenses, the identical sort utilized by Leica and Panasonic Lumix. You are free to combine and match lenses from every model and use them with the BF with none lack of operate. However in case you ask me, the BF is virtually tailored to work with the Sigma I Sequence, a line of small, aluminum barrel primes with focal lengths beginning at 17mm and ranging as much as 90mm. Due to this, Sigma simply up to date the I Sequence in each silver and black to match each the end and typography used on the BF. For the latter, the digital camera’s launch coincides with a model refresh that sees it switching to a pair of customized lighter-weight typefaces, Sigma Sans and Sigma Serif, which are evocative of Garamond.

Sigma left some options out of the digital camera to make manner for its radical industrial design. There is a lengthy checklist of issues the BF would not have, however the notable ones are an digital viewfinder, in-body picture stabilization (IBIS), and a mechanical shutter with flash sync help. Most cameras that price as a lot because the BF have these options and different further perks.

However different cameras do not have the identical clear traces, metallic glint, or high-concept method to design because the BF. It stands out in a crowded market that is self-segmented into two kinds: cameras that look just about like each different mannequin from the ’90s ahead (the Canon EOS R6 Mark II is an ideal instance), and retro-chic ones that mimic previous movie fashions (such because the Nikon Z f and Fuji X100VI).

Sigma’s CEO, Kazuto Yamaki, says the BF identify comes from the phrase “stunning foolishness,” coined by writer Okakura Kakuzo in his 1906 essay “The Guide of Tea.” The phrase describes the ritualistic nature of the Japanese tea ceremony, an occasion that introduces strict, rote actions and actions that elevate a sometimes banal exercise. No, you do not want to undergo the motions as a way to take pleasure in a cup of matcha, however the ritual enhances the expertise to one thing that is effectively past utilitarian. Likewise, the BF digital camera turns into one thing greater than its primary operate due to its outward look.

Time will inform if superbly silly design interprets into success within the market. I am very taken by the BF’s seems to be. It is uncommon to select up a digital camera that is concurrently acquainted to make use of and trailblazing in design, and the BF’s exterior does its job wooing shutterbugs for positive. One word: It is too early to inform if market demand will outpace provide because it has with different fashionable cameras just like the Fuji X100VI, which remains to be on backorder standing greater than a 12 months after market introduction. A PetaPixel report signifies Sigma is simply capable of produce 9 BF cameras per day, a determine that makes me assume the digital camera will probably be briefly provide when shipments begin subsequent month.

Controls: A Radically Easy Interface Wins Us Over

The BF’s cutting-edge industrial design has a robust affect over ergonomics. The aluminum physique has a number of rounded factors, together with a raised thumb relaxation on the rear and an indented nook on the backside proper of the rear plate, the latter of which prevents the digital camera from digging into your palm. The highest and backside edges are sharply outlined. You are in no hazard of injuring your self with regular dealing with; the texture of the BF’s edges is similar to that of a unibody MacBook Professional.

In case you use the digital camera with a wrist strap, the perimeters matter because the BF is certain to spend so much of time in your hand. The BF’s major management floor is its rear dial, positioned below your fingertips, simply to the left and under the thumb relaxation. For granted-handed photographer, I like the location, however I am unable to communicate to how effectively it’s going to work for left-handed creators. Digicam makers hardly ever cater to southpaws, so that is nothing new.

As for the interface, the BF fulfills its promise of retaining issues comparatively easy. As a substitute of burying options in multi-page menus, the digital camera surfaces its settings in a two-strip menu system that runs alongside the highest and backside of the show. So as this menu contains drive, file format, facet ratio, focus, and white steadiness alongside the highest, and shutter velocity, aperture, publicity compensation, ISO, and shade mode on the underside.

The BF is designed so you may change any of those choices with simply your index finger. You will faucet left or proper on the rear dial to scroll via the totally different choices, have a look at the capsule-shaped rear monochrome OLED to see which is energetic, and spin the dial left or proper to regulate the energetic setting. The interface is straightforward and simple, and I haven’t got many complaints about it aside from that the choices will not be configurable or suppressible. I might love to have the ability to shift a few of the positions round; because it stands, ISO, which I virtually all the time depart set to Auto, is smack between EV and the colour mode. These have been the 2 settings I discovered myself adjusting most frequently, and I needed to skip over ISO to commute between them.

If you would like extra granular management over any explicit setting—say, to set a minimal shutter velocity or a spread restrict for auto ISO or toggle eye detection for autofocus—you may go right into a submenu for every top-level setting by urgent the dial’s central button. As soon as there you can change extra settings, both utilizing the dial or tapping digital buttons (within the type of grey round icons). There is a little bit of a studying curve with the method, and I struggled to search out some settings till I found out they have been nested in contact buttons. The on-screen controls to set handbook focus assists, display screen brightness, and different sundries are accessed through one in all these contact buttons, which, whereas wanting like on/off toggles for a setting on the floor, typically present extra depth.

The dial is the primary management floor, however not the one one. The BF additionally places Energy (represented by a single dot), Menu (three dots), and Play buttons on the rear, and a two-stage shutter launch on the highest. Of those, the shutter launch and the spin motion of the dial are mechanical, whereas the remainder of the buttons are touch-sensitive with haptic suggestions. The haptics are incredible, although, and the contact buttons really feel identical to bodily ones. The one outward inform that they’re contact controls is that they present no motion in operation and the haptics do not work when the digital camera is turned off.

The three-dot Menu button opens one other on-screen interface by default. Its prime row units how a lot info is proven on the rear show, and you may toggle publicity info, a middle marker, grid traces, a digital degree, and lens focal size, and set focus distance on or off. Beneath is the System menu the place you will go to format inner storage, enter copyright info to retailer in metadata, set the clock, calibrate the in-camera digital degree, and the like.

I respect that you would be able to make pictures with simply the digital body preview seen, with no info overlay. I did not go fairly that far when utilizing the digital camera, as grid traces are merely essential in my e-book, however even with the grid or a middle marker enabled, the BF’s stay view is clear and freed from distractions. I missed having a stay histogram as an publicity help, although: The digital camera exhibits one in case you open up the shutter velocity or aperture sub-menus, however there isn’t any technique to make it persistent so you will lose sight of it as quickly as you interact autofocus or exit the menu. You possibly can allow full-time zebra or false shade publicity help instruments in its place.

Show: Robust to See on Sunny Days

The BF features a pretty run-of-the-mill rear show: a 3.2-inch contact LCD with 2.1 million dots. The display screen is on par with different cameras on this class, just like the Nikon Z f, which matches the BF in dimension and backbone. Nonetheless, the Z f and most different mirrorless cameras help some degree of display screen articulation and embrace an eye-level viewfinder, options lacking from the BF.

The sensible result’s that the BF’s show is simply exhausting to see on a brilliant, sunny day. There isn’t any technique to reposition the LCD to keep away from glare, and with out articulation, you will have to both view it from an askew place or get down in your fingers and knees to border pictures from floor degree as obvious brightness and distinction fall off when seen from an off angle. Even with the brightness set to most and the out of doors view help turned on, I had to make use of my left hand to defend the show when making pictures outside on a brilliant day.

I count on some photographers to think about the BF a platform for classic, mechanical lenses. It is simple sufficient to connect any previous SLR or Leica M rangefinder lens through a cheap adapter, and the BF seems to be incredible with an vintage lens connected. I attempted it with the Leica Summicron-C 40mm F2 from the Nineteen Seventies with superb outcomes.

For handbook lenses, the BF helps each body magnification (2x, 4x, and 8x can be found) and focus peaking as focus assists; simply double-tap a spot on the rear show to activate it. I discovered it straightforward sufficient to set focus exactly with a 4x or 8x zoom, although the latter resulted in a jittery preview. By default, the BF solely leaves the magnified view up for a brief two seconds when utilizing a totally handbook lens, however you may change it to “Maintain” and depart the punched-in view up for so long as it is advisable set focus. A half-press of the shutter returns to the unmagnified, full-frame view.

It is as much as you whether or not an EVF is a must have digital camera function. I missed having the choice to deliver the digital camera as much as my eye when taking pictures on a brilliant day and when manually focusing. It would not assist that my eyes, like the remainder of me, at the moment are of their mid-40s, and progressive lenses can solely accomplish that a lot to deliver a 3.2-inch LCD into sharp view. In case your eyes are youthful and see shut objects extra clearly, it’s possible you’ll discover it simpler to stay and not using a viewfinder. The screens on flagship smartphones are simpler to see outside, and I am disenchanted that Sigma did not put a greater show into the BF to make up for the shortage of articulation and eye-level viewfinder.

Energy and Connectivity: Quick on Battery Life

Sigma made a brand new, customized battery for the BF, the BP-81, which installs straight into the underside plate. The BP-81 is a tall, cylinder-like battery that pops out with the flick of a toggle swap and is rated by CIPA to ship 250 footage per cost. In testing, I discovered the battery to have much less endurance. In my first devoted outing with the BF, I knocked down energy from 100% to fifteen% over the course of about three hours and solely walked away with 130 footage. On my common half-hour photograph walks round my neighborhood I repeatedly noticed the battery drop off by 10% or extra with a handful of pictures to indicate for it. In brief, the BF simply chews via the battery, particularly when used outside with the display screen brightness at its most setting. I noticed higher outcomes with video; with commonplace display screen brightness, the BF data about 110 minutes of 4K30 footage on a full cost and does so with none overheating warnings in a room-temperature surroundings.

Due to this, I think about a spare battery to be a crucial accent. Sigma has not but acknowledged how a lot a spare BP-81 will price. The battery prices in-camera through the USB-C port and takes a while to take action. I clocked it at two hours to go from 0 to 90% and a pair of.5 hours to get to 100% when plugged right into a 100W charger. Sigma sells an exterior, twin battery charger individually, however likewise has not but supplied pricing particulars. Simply word that in case you use a tripod quick-release plate together with your digital camera, you will possible should take away it to swap the battery out, as its launch swap is positioned simply subsequent to the tripod socket.

For connectivity, the USB-C 3.2 port is it. The connection is used for knowledge switch (at as much as 10Gbps) and webcam streaming through the UAC/UVC commonplace. The BF depends on inner storage and contains 230GB, sufficient for 14,000 JPGs, 4,300 DNGs, or about 2.5 hours of 6K30 video.

Sigma doesn’t embrace a USB-C cable or energy adapter with the BF, solely the BP-81 battery and an aluminum physique cap. Physique caps are sometimes product of light-weight plastic, so Sigma’s alternative to make use of aluminum is an aesthetic contact, particularly because the cap completely matches the digital camera’s end.

Digital cameras began getting Wi-Fi and smartphone app help a little bit greater than a decade in the past, and within the interim, wi-fi connectivity has turn into a primary, anticipated function. Sigma opted to forgo wi-fi help with the BF, but it surely’s not as a lot of a shortcoming as you’d assume. In case you plug the BF into an iPhone, iPad, or Android gadget with a USB-C connection, you may offload footage straight, simply as you’d with a pc, with out the necessity for an additional app.

Chances are you’ll run into an issue when you’ve got an older cellphone; I used to be not capable of get my iPhone 13 to speak with the BF utilizing an official Apple USB-C to Lightning cable, however have seen studies that utilizing a USB-C to USB-C cable at the side of Apple’s official adapter works. I had a better time with a Samsung Galaxy Tab S9 Extremely pill, on which the BF exhibits up as a USB storage gadget within the Information app. However I count on different digital camera makers to observe go well with and add help for USB-C connection to newer good gadgets, given simply how straightforward the method is.

Autofocus: It Does All of the Work For You

Sigma’s transfer for a extra primary, easy interface extends to the autofocus system. Whereas many cameras supply a litany of focus field sizes, monitoring, and topic recognition choices, the BF’s focus system is pared down with out getting in the best way of performance. Many of the esoteric autofocus choices in mainstream cameras just like the Sony a7C II and Nikon Z6III are finest used for difficult scenes like workforce sports activities and wildlife. The BF is not a great digital camera to make use of with the massive, heavy lenses these disciplines require, so it’s sensical to go for a pared-down focus system. The BF succeeds in retaining autofocus easy. You possibly can let the digital camera decide focus by itself (practically the whole thing of the body is roofed by a hybrid contrast-phase detection focus system) or prohibit it to a small, versatile spot. I opted for the full-frame focus space virtually completely, and it labored extraordinarily effectively.

Face and eye detection kick in mechanically for folks and pets (you may flip them off in case you favor) and virtually all the time discover the goal. If not, it is only a matter of tapping on the display screen to direct the main focus system to a topic. In case you’re utilizing the smaller focus space, doing so merely repositions the main focus field, and in case you use the full-frame protection it redirects the main focus briefly. If you wish to revert to the complete space of protection, you simply should faucet cancel on the prime proper nook of the LCD; this icon is simply seen once you’ve overridden the complete focus space with a contact motion.

The BF’s focus system is quick sufficient to help 8fps steady drive with focus and publicity at each body. It is from the quickest digital camera on the block—the L-mount Lumix S5 II helps 30fps drive with focus and publicity, for example—however in my expertise, 8fps drive is greater than ample for the kinds of pictures creators are prone to make with the BF.


Imaging: Pleasing Shade Profiles, However No Flash Assist

The BF makes use of a full-frame 24MP BSI CMOS sensor with a totally digital shutter readout to seize pictures. The sensor tech is confirmed, as Sigma makes use of the same chip in its fp digital camera and in L-mount our bodies just like the Lumix S5 II and Leica SL3-S. The BF covers the same ISO vary (100-102400) and matches up with different cameras with 24MP BSI CMOS chips for picture noise and dynamic vary.

Sigma 90mm F2.8 Modern, f/2.8, 1/4,000-second, ISO 400, Wealthy (Credit score: Jim Fisher)

The BF’s small body leaves no room for in-body picture stabilization (IBIS), a function most different full-frame mirrorless cameras embrace. With out IBIS, you will have to take care to make use of shorter shutter speeds to freeze movement and can wish to use a tripod or discover a flat place to set the digital camera for longer exposures.

Its 14-bit uncooked DNG pictures present essentially the most leeway to edit shade and publicity within the decrease register (ISO 100-3200), in addition to the least quantity of luminance noise, the digital model of movie grain. Pictures get extra pronounced noise and fewer room to elevate shadows or reign in overexposed highlights from the ISO 6400-51200 vary. Image high quality is on the tough facet on the most (ISO 102400), however you are solely prone to push the sensitivity that top when making pictures in dimly lit interiors.

The JPG output follows go well with, with the caveat that the 8-bit compressed file format leaves little or no room to edit publicity at any ISO. In-camera noise discount cuts out grain at greater settings however also can wipe away element and provides footage a waxy, clean end once you push the ISO towards its higher restrict.

One word on ISO: Most cameras default to the bottom commonplace setting if there’s sufficient mild coming into the lens to help it. Sigma tuned the BF’s automated settings in another way as a result of the sensor’s dynamic vary is broadest round ISO 320. Due to this, the BF tends to favor a setting round ISO 400 and really brisk shutter speeds in brilliant circumstances. I do not see any draw back to the method, and you may all the time change to a handbook setting if you would like; it is simply good to know the logic behind the choice, particularly because it’s in distinction to how most different cameras work.

The BF depends on a totally digital shutter to make pictures, as its slim physique leaves no area for a mechanical focal aircraft shutter. Its 24MP BSI CMOS sensor scans rapidly sufficient to keep away from rolling shutter movement distortion in most situations. I noticed clear, straight traces in automobiles driving laterally throughout a body in a 35mph velocity zone, for example, however you may count on to see some curved Jell-O impact in case you level the digital camera at topics shifting throughout the body at a brisker tempo. I do not see this as a significant deterrent for on a regular basis images, nonetheless.

Sigma 50mm F2 Modern, f/2, 1/125-second, ISO 125, Wealthy (Credit score: Jim Fisher)

I peg the shortage of flash help as a extra severe consequence of the totally digital shutter. Including flash help would require Sigma to make use of a quicker studying sensor with stacked CMOS tech behind it or add a mechanical focal aircraft shutter, in addition to a sizzling shoe or sync port, to the physique. Any of these would add price and bulk to the digital camera, so I see the reasoning behind leaving them out. In case you’re thinking about experimenting with flash images, you are higher off with a full-featured mirrorless digital camera just like the Canon EOS R6 Mark II, the Nikon Z f, or the Sony a7C II, or going for a compact physique with a built-in flash and leaf shutter just like the Fuji X100VI.

The BF helps DNG seize so you may tone pictures to style, both with a desktop Uncooked processing app like Adobe Lightroom Basic, a smartphone app, or the BF’s in-camera improvement instruments. You are capable of reprocess any DNG picture with one of many BF’s curated shade profiles, which embrace the fundamentals just like the impartial Normal look, vivid Wealthy profile, a mushy Calm end, and black-and-white Monochrome possibility, plus filtered profiles like Cine, Basic Blue, Basic Yellow, Forest Inexperienced, Powder Blue, Rec.709, Sundown Crimson, Teal & Orange, and Heat Gold. I notably preferred utilizing Wealthy for flower and plant pictures at a botanical backyard, Sundown Crimson for early morning walks, and Monochrome for scenes that look higher in black-and-white than in shade. Every profile is configurable to style, because the digital camera allows you to intensify or diminish the general firming and tune spotlight, shadow, fade, and vignette results.

Video: Lacking the Connectivity Vloggers Will Need

I am unable to assist however consider the BF as a digital camera that is finest fitted to capturing stills, however that did not cease Sigma from placing some severe video options inside. The BF data 10-bit video with H.265 encoding and 8-bit footage in H.264 at as much as 6K30, with 4K30 and 1080p120 obtainable as effectively. All the nonetheless picture shade profiles can be found for films, plus a flat L-Log look with decrease distinction and saturation that gives a impartial start line for extra malleable shade grading within the enhancing room.

Digital picture stabilization (EIS) is offered for 4K and 1080p video recording and works to clean out jitters and jumps that we see in unstabilized handheld video, with the caveat that utilizing EIS introduces a 1.25x crop to the width of your body. Basically, it makes your wide-angle lenses rather less wide-angle.

The BF could discover a good house in streaming setups, nonetheless. Its USB-C connection makes it straightforward to plug into a pc to make use of with OBS or to file a YouTube studio present. Within the discipline, it’s also possible to use an exterior microphone or join headphones to observe audio from the in-camera mic. The built-in mic is OK for brief clips and social footage however picks up loads of background noise and sounds hole when put next with an exterior mic.

When you actually can use the BF as a video digital camera, I do not suggest it for vloggers or indie filmmakers. It merely would not have the accent ports it is advisable construct out a video rig. Having only one connection for audio is way too limiting, and there isn’t any place on the physique to mount an exterior microphone. There are many alternate options to think about on the value level for video, together with cameras with inner ProRes encoding and full accent help, just like the Lumix S5 IIx, Nikon Z6III, and Fujifilm X-H2S.

Verdict: A Lovely Digicam Constructed for a Slim Viewers

The Sigma BF’s exterior design, tightly centered function set, and streamlined person interface place it as a digital camera constructed for a sure sort of photograph fanatic, specifically one that desires to make use of a ravishing instrument to take footage. It really works finest with small prime lenses and is most fitted to on a regular basis slice-of-life pictures, landscapes, superb artwork abstracts, naturally lit portraits, and comparable pictures. If Sigma had managed to work in an EVF or a tilting display screen, I might go so far as to say it is a great instrument for the kind of pictures I wish to make personally. Total, I had fun utilizing it, and I am keen on the colour profiles Sigma makes use of in its JPG engine, however battery life is an excessive amount of of a sticking level for the BF to earn prime marks. The Nikon Z6III merely does extra, runs longer, and balances higher with telephoto and zoom lenses, so it retains our Editors’ Selection award, however I will not fault anybody for choosing the BF as a substitute. There’s nothing silly about selecting magnificence over practicality if that is what your coronary heart wishes.
