In February, Sigma introduced the Sigma BF. It's a full-frame, interchangeable lens digicam with only a shutter launch, a dial and three buttons. That minimalism speaks to me, and I felt the BF was doubtlessly transformative. Images is one among my favourite hobbies, and I've all the time felt fashionable cameras are too sophisticated. Once I acquired a unit of the Sigma BF to check, I wished to adore it. Sadly, it is perhaps too easy.
All of it begins with the design. The Sigma BF is among the business's few unibody cameras. It's carved from a single slab of aluminum, a course of Sigma says takes seven hours to finish. The result’s a digicam in contrast to any I've used earlier than, with construct high quality that surpasses both of my present Fujifilm fashions, the X-E3 and X-S20. Now, I do know what you're considering: The BF appears to be like like an ergonomic nightmare. Surprisingly, it's not too dangerous, due to the inclusion of two beveled edges the place your palms meet the underside of the digicam physique.
Nonetheless, it's lacking a couple of options that will have made it extra snug to make use of, doubtless because of the limitations of its unibody design. For one, a correct grip would have been good, particularly while you're utilizing a heavy 50mm lens just like the one Sigma despatched me for testing. The BF can also be lacking a sizzling shoe mount, so third-party thumb grips are off the desk. Most annoying of all, it solely has a single strap eyelet, so for those who don't wish to use a neck strap, you'll want one which attaches to the digicam's tripod mount. I don't personal a kind of, so I needed to carry across the $2,000 BF in my hand your entire time I used to be utilizing it. You possibly can think about how that felt.
The BF provides a really totally different taking pictures expertise out of your typical digital digicam. As I discussed, it has solely a shutter launch, a single dial and three buttons (one for powering the digicam on and off, one for reviewing your photographs and photographs and one for accessing the overflow menu). There's additionally a touchscreen, however you wouldn't comprehend it at first, as a result of apart from when choosing a spotlight level and toggling some choices, you gained't be utilizing it a lot whereas taking pictures.
The BF's one dial is the first option to work together with the digicam. To regulate your publicity, you first press left or proper on the dial to cycle to a particular setting, after which spin it to tweak the degrees as desired. A second smaller display above the dial lets you alter these parameters with out interacting with the principle show.
Alternatively, you possibly can press down on the middle of the dial to open the BF's "twin layer" menu system. Because the identify suggests, Sigma has organized most of what you would possibly want throughout two ranges of menus. For instance, say you wish to swap the digicam from matrix to identify metering. That entails urgent down on the dial, scrolling over to one of many publicity settings, tapping the middle of the dial once more, after which utilizing your thumb to press the touchscreen and allow spot metering. Accessing many of the settings you'll want gained't be as tedious, however this worst case situation demonstrates the place the expertise of taking pictures with the Sigma BF falls quick.
The BF isn't nice for capturing fleeting moments. In ditching many of the bodily controls fashionable cameras are identified for, the Sigma BF makes it troublesome to vary a number of settings concurrently. I used to be most aggravated by the BF each time I wished to shoot a fast-moving scene.
On one among my photograph walks with the Sigma BF, I noticed a father using a motorbike along with his son within the seat behind him. With my X-E3 or almost another digicam, capturing that second would have been easy. I may have modified the drive mode, focus system and shutter pace independently of each other. On the BF, I needed to alter every setting consecutively. By the point I used to be accomplished, the daddy and son have been lengthy gone.
Among the BF's shortcomings could possibly be addressed if Sigma no less than allowed you to edit the short settings display to indicate fewer choices. I don't want easy accessibility to vary issues just like the facet ratio, for instance. In 2025, each new digicam ships with a very bloated menu system, and in that regard the Sigma BF is a breath of recent air. Nevertheless, permitting the person to make their very own tweaks would have made for a a lot better expertise.
And that’s the factor: With the BF, Sigma breaks digicam interface conventions which are conventions for good motive. Let me offer you one of many extra irritating examples: The digicam inexplicably doesn't supply a straightforward option to measure the publicity of a scene. There was no meter to point whether or not I used to be about to under- or overexpose a shot, and I couldn't add one to the principle display.
The one means I may see a histogram, my most well-liked technique for nailing publicity, was to entry the second layer of the interface from one of many seize settings. That is an particularly confounding resolution as a result of you possibly can half press the shutter to make fast publicity compensation changes with the management dial, however as quickly as you do, the BF jumps out of no matter menu you have been . If digging by way of menus isn't your factor, there are two reside view overlays you possibly can allow to see for those who've clipped your shadows or highlights. The primary is your regular zebra sample. The second, which Sigma calls False Coloration, turns many of the display grayscale and makes use of warning colours. Neither felt as exact as a correct publicity meter or histogram.
On paper, the BF is a good digicam for video, with help for 6K recording, HEVC encoding and L-Log. Sadly, the BF's minimalism is a weak point right here too. To start out, framing a shot is a problem for the reason that digicam has a set display. Getting usable footage can also be tough. The BF doesn't supply in-body picture stabilization, and whereas there are a couple of L-mount lenses with built-in stabilization, most wouldn't be sensible to make use of with the BF as a consequence of their dimension and weight.
For those who've gotten this far, you're in all probability questioning if I’ve one thing constructive to say concerning the BF. Nicely, the most effective factor concerning the digicam is that it takes genuinely nice photographs, which is what makes all its shortcomings all of the extra irritating. The 24-megapixel, bottom illuminated sensor and Sigma's lenses seize and render element fantastically with out being medical. The BF additionally has nice topic detection autofocus that makes taking pictures portraits of individuals and pets simple.
The Sigma BF has some fascinating concepts about what a digicam can appear like in 2025, however these concepts are sometimes marred by poor execution. As a primary stab at a minimalist digicam, the BF has sufficient going for it, and with refinement, I may see future variations evolving into one thing particular. For instance, I’d like to see Sigma discover a option to embody a flip-out display within the BF's unibody body. Till then, $2,000 is so much to ask for a digicam that could possibly be a lot extra.
