Initially, the three lenses were made available in Canon EOS-M, L-Mount, Micro Four Thirds and Sony E-mount fittings. The Fujifilm X-mount version arrived in 2022, followed by the Nikon Z mount versions in April 2023. As you might have guessed this Sigma 30mm f/1.4 EX DC lens is a little bit soft wide open at f/1.4, but still totally usable. The edges suffer the most from the softness, but the center of the frame is not to bad. The softness slowly goes away as you approach f/2.8, and then it’s nice and sharp across the whole frame. Beyond f/2.8 is solid all the way up and pretty much tac sharp at f/4-f/16. Can’t beat that for the price 😉 The focusing of this lens is also very good and accurate. When shooting wide open at f/1.4, the focus is critical as the depth of field becomes super narrow. I missed several shots because I did not account for how shallow the DOF actually was. The Sigma 30mm f/1.4 EX DC lens is not a light lens either considering it size. The weight is expected though as the f/1.4 aperture is large, and calls for 7 large SLD glass elements to make up the lens group. All that glass adds up to a pretty hefty little lens that tips the scales at 15.17 oz (430g).

shot was taken as close to the subject as focusing allowed; In this case, 10.4" or 264mm, measured from the front of wider than F/2.8. Almost half the frame is soft at F/1.4-F/2. The above crops were taken at dead center and focused In this Hands On Sony Lens Review of the Sigma 30mm f/1.4 EX DC Lens I will cover everything you need to know, from a “Real World” Photographers perspective!! Here’s what it looks like mounted to the Canon T3i and the Sony Alpha A55 for comparison. Also worth noting is the finish on the Sony version of this lens is a bit different. It has almost a soft textured finish on it that the Canon version of this lens does not have. See below for a closer look at what I mean. Sigma 30mm f/1.4 EX DC Lens on Canon T3i Sigma 30mm f/1.4 EX DC Lens on Sony Alpha A55Lightweight in build and selling price, this is a high-performance standard prime that combines very good build quality and nice handling characteristics with solid all-round performance. Autofocus is fast and accurate, yet smooth and virtually silent for movie capture. Image quality is excellent overall although, as is usually the case with fast prime lenses, axial chromatic aberration can be noticeable when shooting wide-open. All things considered, this Sigma is terrific value at the price. Part of the DN range of lenses for mirrorless cameras, the Sigma 30mm f/1.4 DC DN C ( Sigma 30mm f/1.4 DN) is a fast- aperture, third-party standard prime for Sony E-mount cameras. Taking into account the 1.5x crop factor on Sony APS-C sensors, the Sigma 30mm f/1.4 lens offers an equivalent 45mm focal length, making it a good option for a variety of subjects, including portraits and general use. Any lens with a large aperture is begging to be used wide open. Indeed, while I was interested in seeing how the lens performed at f/5.6-f/11, the larger apertures proved to be the most interesting.

Same thing happened a bunch of months ago with one of the A7's and the /1.8. It was embarassingly off centre and DPReview reran the test with a new lens. Nice, that Sigma is more aiming for the APS-C mirrorless market... maybe there will be an X-mount version of this lens soon.

I’ve shot with this thing for hours straight in the city and haven’t had any issues with comfort. When hiking, I can toss it easily in my bag. All three lenses defend themselves well from flare and ghosting. I only came across a few examples when shooting into direct sunlight, the worst of which you can see below. Otherwise it didn’t present an issue.

It's noticeably a little wider than a 50mm lens on a full frame camera, so the focal length is not exaggerated, Color fringing towards the edges and corners is fairly minimal and auto corrections are available in current and recent Canon and Nikon DSLRs. As to be expected with a bright aperture prime, the Sigma experiences some heavy vignetting wide-open, with 1 1/3 stops light lost in the extreme corners. The good news is stopping down even to F1.8 shows a great improvement. The Sigma 30mm F/1.4 EX DC (made in Japan) is made to be used on an APS-C body only, and will produce

note; the lens doesn't seem to stop down correctly at F/11-F/16, and causes about 2/3 of a stop underexposure at those apertures. some bad news though; the very centers are sharp as stated above, but the image periphery is very soft, especially at apertures Not only is it incredibly sharp, but even the bokeh looks good. While not quite a telephoto, the lens renders beautiful bokeh balls that allow for excellent subject isolation.In terms of chromatic aberration, the Sigma puts up a fairly decent performance. There is some lateral CA but this is easily removed, either by the camera or most editing software. Another trade-offforhavingan F1.4 maximum aperture in a relatively small lens is fairly severe barrel distortion that is easily detected in any scene with straight vertical elements. Without correction, it has potential to be a bit distracting. As I stated, it’s survived dozens of adventures in inclement weather, been bumped against tons of hard surfaces, and has probably summited more mountains than some people ever will in their entire lives. up when the sun is close to the image, about the same as other lenses with this basic focal length.
