Optically, the Sigma 56mm f1.4 is as good as I would expect from a modern lens on a mirrorless camera – it’s pin-sharp where it needs to be. I’m not a pixel peeper and don’t pay particular attention to the very edges of the frame because they are rarely necessary to me. What I am concerned about is the autofocus. Thankfully, the Sigma performs as well as I would expect – it doesn’t miss a beat and is rapid. Unless you’re shooting sport at f1.4, you won’t find any issues with the autofocus. The Sigma 56mm f1.4 autofocus is also almost entirely silent. Sigma 56mm f1.4 Fujifilm X Mount Specifications As a lens manufacturer, we will continue striving to meet the expectations of our customers with an expanded lineup of lenses and mounts for mirrorless cameras. Sharpness remains excellent all the way through to f/11, but drops off at f/16 due to diffraction (Image credit: Matthew Richards) As expected, sharpness increases as the lens is stopped down a bit but I found this to be a clear winner in sharpness even at f/1.4. Naturally, it’s not all about sharpness. When using a wide aperture to gain a tight depth of field, the bokeh, or quality of defocused areas, can be equally important. The Sigma excels here again, with a wonderfully soft bokeh and a nicely smooth transition between focused and defocused areas. An added bonus is that there’s extremely little axial chromatic aberration, even when shooting wide-open. In this respect, it performs rather better than the Sigma 30mm f/1.4 Contemporary lens.
The X-mount version of the lens measures 72.2mm (2.8”) in diameter, 92.6mm (3.6”) long and weighs 405g (14.3oz). 30mm F1.4 DC DN | C The Sigma 56mm f1.4 lens has several features that make it stand out. These include a fast maximum aperture of f/1.4, which allows for excellent low-light performance and a lovely shallow depth of field. It also has a high-quality optical design with 10 elements in 6 groups, including two SLD elements and one aspherical element, which helps to reduce chromatic aberration and distortion. The lens has a silent autofocus motor and a manual focus override option. What cameras are the Sigma 56mm f1.4 lens compatible with? As for the autofocus, the 56mm f1.4 DC DN Contemporary uses a stepping motor to provides fast and near silent focusing. I tried the focusing in a variety of conditions, and overall, I found the autofocus to be drama free. It is also very accurate, which is particularly important considering this lens produces a shallow depth of field with its f1.4 aperture.
Fujifilm GFX100 II in-depth review
With the camera set to aperture priority, I photographed a variety of locations to see how the lens performed in this manner and was really pleased with the detail captured. As expected, at f/1.4, the depth of field is very narrow and produces a buttery softness surrounding the focus point. The short length balances especially well with the compact mirrorless camera bodies it’s designed for. The Sigma 56mm f1.4 lens is designed specifically for Fujifilm X-mount cameras, including the X-T4, X-T3, X-T2, X-T1, X-H1, X-Pro3, X-Pro2, X-E3, X-E2, and X-E1. It is not compatible with other camera systems. What types of photography is the Sigma 56mm f1.4 lens best suited for? I’ve owned Sigma lenses before when I used to shoot on Nikon, so I already had a bit of trust that Sigma would deliver another decent lens. The Sigma 56mm is small and light, and although it’s got an excellent build quality, it doesn’t feel as solid as the Fujifilm lenses I’m used to. It also has a matt finish, which doesn’t look as nice at home on the front of my Fuji, but I can accept that, given it’s got the classic finish of a Sigma lens. Control algorithms including AF drive and communication speed optimisation have been developed specifically for X-Mount interchangeable lenses. In addition to supporting high-speed AF, the lens also supports AF-C (Continuous AF) and in-camera aberration correction (supported cameras only).
The Sigma 30mm F1.4 DC DN lens for Fujifilm X-mount is constructed of nine elements in seven groups, including two aspherical elements. It features a nine-blade aperture diaphragm, offers a minimum focusing distance of 30cm (11.8"), has an aperture range of F1.4 through F16 and uses a 52mm front filter thread. The 56mm f1.4 is the longest of the trio and gives you an equivalent focal length of 84mm, making it particularly ideal for portrait photography. If you’re a DX user, then the nearest you’ll get to this focal length from a proprietary prime lens is the Nikkor DX 24mm f/1.7 lens, or, you might instead use something like the Nikkor Z DX 50-250mm f/4.5-6.3 VR lens or the Nikkor Z DX 18-140mm f/3.5-6.3 VR lens. Alternatively, you might consider mounting the Nikkor 50mm f/1.8 S lens, which would give you an equivalent of 75mm on your APS-C camera, but will cost you a little bit more, and is quite a lot larger than the Sigma 56mm lens. The 56mm f1.4 also scored highly in term sod optical performance. The images it produces are superb, and in every way, I feel this lens compares very favorably with what Fujifilm offers. I don’t own any of these other lenses anymore, I just have Fuji’s 56mm. It gets out of my way and lets me focus on my shoots.”It can be tempting to go for a third-party lens because it’s cheaper. But sometimes, it’s not always the better bet. A good friend of mine recently bought the Tokina 56mm for Fujifilm. He loves it, and that’s fine. It’s super affordable and he’s getting great photos with it shooting comedy shows in NYC. He brought it with him the last time we met up. I set it to continuous autofocus, and the lens couldn’t focus at all. It only worked in single autofocus. There’s also no full weather sealing, which is fine for him. But in the long run, he might see differently. Combined with the bokeh achieved at the minimum aperture of f/1.4, this lens creates some beautiful portrait images. Along with the sturdy design of the Sigma 56mm f/1.4 comes a high degree of weather and dust sealing – another big advantage.

I think all of us photographers just yearn for and seek a set up that allows us to purely concentrate on our work. For me, there are other lenses that do that for me. But that is the unique aspect of photography. There so many photographing styles and so much variety in gear.
Chromatic aberrations were also traced along high-contrast edges at f/1.4 when in-camera corrections were turned off. Some mild traces of purple and green fringes of colour were still obvious in shots where the built-in lens profile was applied, so you may find yourself applying some additional manual correction, just as I did.

Straight off the bat, there is a clear difference in our ideology and expectations of a lens. Where as I am looking for basically the same version of my Samyang 21mm but as a slight telephoto, Jaco is mainly interested in the compression and FOV. Compression is only slightly important to me, and it’s avoiding the wide angle distortion that has me reaching for the other camera and lens or zooming in more. But compression is not something I think of very often. Sigma did announce they would be making their APS-C mirrorless lens trio (16/30/56) for the Fujifilm X-mount at some stage in the future. I don’t know what politics are at play but it seems bizarre to me that they haven’t done so already, or don’t feel like they should be doing so with more haste. Especially after I read the other day that they have released those exact lenses for the L-mount. Which is a complete dead end for APS-C lenses. Absolutely bizarre. So, in terms of build and ergonomics, the 56mm f1.4 DC DN Contemporary scores high in my book, and to top it off, it even comes with a lens hood that matches well in terms of size. I tried it, and it works quite well with the lens. It doesn’t get in the way, and it isn’t overly bulky. Sadly, the Sigma 56mm isn’t weather-sealed. There is a gasket at the mount to prevent some dust and moisture from getting in, but there is no further weather sealing in the lens barrel, so you might want to avoid shooting in adverse conditions. Talking of the mount – it’s made from brass. Performance
