As well as being made in the usual Canon, Nikon and Sigma mounts, it’s also one of Sigma’s new lenses to be offered in E-mount for Sony users, ruling out the need for a Sigma MC-11 converter. The Sony E-mount version performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction, with the benefit of it also being compatible with Sony’s continuous AF modes, which are not supported by the MC-11. Sigma 40mm f/1.4 DG HSM Art review: Build & Handling This is really what we are usually paying/looking for. The optical quality of the lens. I can’t talk with any authority on groups of elements and types of glass, it all means very little to me and I couldn't offer anything new to what is already out there. What I can talk about though is how it handles common situations. The Canon 35 f/2 IS has perhaps the smoothest bokeh of any of the 35mm options, but I don’t see a major advantage in this kind of testing – and that bodes well for both these lenses. The bokeh highlights from 35IS look remarkably similar to those of the 35L II.

There is one figure here where Sigma lags behind several competitors that I will note, and that is in minimum focus distance/maximum magnification. This has been and continues to be an area of strength for the 35mm focal length. 85mm lenses typically have very poor figures here (a maximum magnification figure of .11-.13x is common), and even 50mm lenses (where the standard used to be around .15x), but 35mm lenses have always bettered those figures. The Sigma’s ability to focus down to one foot/30cm and have a .20x magnification (1/5th life size) is useful, but not nearly as useful as the Canon 35 IS at .24x and is doubled by the Tamron’s .40x figure (one of the greatest strengths of that lens!). Above: One last close-up test with each lens focused as close as it would allow when set to manual and with the apertures wide-open. Here’s the Sigma 35 1.4 from about 30cm away where it’s reproducing 162mm across the frame. It’s fairly sharp in the middle but becomes quite soft at the edges where I needed to stop it down to f4 to f5.6 for a good result at the extremes.I reviewed the new Tamron SP 35mm f/1.8 VC a few months and was very impressed by it. It has a somewhat smaller aperture value (f/1.8) but offers up a professional grade, weather sealed build quality, great optics, and adds an image stabilizer to the mix. It also retails for three hundred dollars less.

I had a Sigma 30mm F1.4 and found that F1.4 was useless for me. Reviewing all of the F1.4 images above the only one that I don't think would look better at F1.8 or F2.0 is the boy with the bubbles. I find the razor thin DOF of F1.4 to be quite annoying in the other shots. I do appreciate looking at photos that other people have taken at F1.4 and finding the same annoyingly too shallow DOF.

The Sigma 24-35mm f/2 ART is also an interesting alternative. It has a slower aperture but delivers similar image quality along with a small zoom range. I reviewed it here. It retails for a hundred dollars more. Build quality is good, as we've come to expect from Sigma's recent prime lenses. The magnesium alloy-bodied 35mm F1.4 feels very rugged, with a well-constructed, premium feel. Its physical controls – and especially the large, nicely-damped, buttery-smooth focus ring – reinforce that feeling. I have had lenses in the past that have had a fault. When ever I have had them repaired they have always broken again. It's like the fault is produced at point of build. I had a nightmare with a Canon 1.4 lens. My ethos now is that if a lens has a fault, replace it outright. No science behind this belief mind haha.

Both E-mount and L-mount versions of the Sigma 35mm F1.4 are very sharp lenses, and in most respects can deliver great image quality even when shooting wide-open. Although there are issues with ghosting and cat's eye, in many situations you'll be able to work around these. The Sigma 35mm F1.4 DG DN Art isn't quite as compact and lightweight as we might have expected, given that it's designed specifically for mirrorless. Compared to the original DSLR-oriented 35mm F1.4, its barrel diameter is near indistinguishable and its weight has only dropped by around 20-25 grams (0.7-0.9 ounces). As noted in the previous section, the size and weight advantage versus the mirrorless variant of Sigma's older design is rather more noticeable, however. He had the same problem with a 50 Art as well. And one of his friends, another wedding photographer, had a 50 that loosened up on him. This Sigma lens is ideal for photographers looking to get an optically excellent lens at a great value. It’s great for any photographer who needs a fast 35mm lens for a full-frame camera, such as for weddings, events, and portraits. It’s also a really great lens equivalent of 50mm on a crop sensor, but you can save even more money buying a DX 35mm lens for crop bodies. why bother with a lens - my eyes are the most 'perfect' view I've ever used. But it weighs a ton considering the complete system 🤣This review is based on my experience with the Nikon version of the Sigma 35mm f/1.4 ART lens. You can extrapolate this information for other versions, such as the Canon or Sony copies. I own both a Sony and Oly m4/3 there where really no competition, the images where not just sharper, the images had more contrast, better saturation, more DR, less noise, better colours with a better transition of the colours etc… A bigger concern is the Sigma's modest autofocus performance, especially when compared to Sony's very swift-focusing G Master lens if you're an E-mount shooter. And videographers will also want to bear in mind its significant focus breathing, although that's also an issue for the Sony lens to a somewhat lesser extent. This lens is extremely amazing! It's sharp as hell! I just recently bought this lens 4 months ago, it focuses really fast. OPPO's mid-range smartphone aims to provide a sophisticated camera system at an attractive price. Andy Westlake sees how it measures up.

If using the Sigma 35mm f/1.4 Art for an especially critical shot, Live View focusing can be utilized to ensure your subjects remain in focus. Because Live View uses the actual data processed by the sensor to achieve focus, any issues with traditional phase-detect AF are bypassed. It may look silly when you're holding your DSLR up like a compact camera, but... the in-focus result will likely be worth the small embarrassment for fleeting moments. When comparing the Sigma 35A and Canon 35L II side by side at a wide open f/1.4 aperture it is actually surprising how similar the bokeh highlights looked. The shape of the highlights is roughly the same, and while there is just a hint of additional busyness in the Sigma’s highlights, that is only detectable at 1:1 pixel level. The Canon shows a slight bit more concentric rings while the Sigma shows more of a pattern. As you move away from the center of the frame both lenses show a tendency towards lemon shapes instead of circles – a pretty common phenomenon. At identical exposure the Canon’s image is noticeable brighter, but probably no more than a quarter stop.Above: Moving into the far corner also shows a similar result when they’re at their maximum apertures and coincidentally both lenses capture almost exactly the same field of view – remember just because the model quotes the same focal length, doesn’t mean the coverage will be identical in practice. Don't get me wrong - I'd buy any better, smaller and lighter lens in a heartbeat - I am completely brand agnostic - I buy whatever is best - only one sigma lens thus far and this is going to replaced soon when we'll get a GM macro from Sony - I am expecting this might beast all existing macro lenses by a good deal - given the pedigree of recent lens releases. For testing purposes, the Sigma 40mm f/1.4 DG HSM Art was predominantly paired up with Canon’s 50-million-pixel EOS 5DS R Incredibly smooth focus ring Macro focusing is possible to a respectable minimum distance of 30 cm (11.8"), which is sufficient to provide a maximum magnification of 0.19x (1:5.4). Objektiv používám krátce, ale jsem s ním velmi spokojená. Má krásný bokeh a velmi pěknou ostrost již od nejnižší clony. Překvapila mě i pěkná hloubka ostrosti, působí někdy dojmem, jako by bylo foceno delším ohniskem.
