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. The optical path includes nine elements in seven groups. Two of the elements are aspherical but the lens features neither FLD (Fluorite-grade Low Dispersion) nor SLD (Special Low Dispersion) elements, often used in Sigma lenses to boost sharpness and contrast, while reducing chromatic aberrations. 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

How important is the hybrid AF and face detect features of the Sony AF system to you? If these are important to you, then you will definitely want a native Sony, or Zeiss, lens that utilizes 100% of the AF feautures. Conversely, if you shoot mostly static scenes and don’t value face detection highly, then Sigma for E-mount is certainly an option for you. We run a range of lab tests under controlled conditions, using the Imatest Master testing suite. Photos of test charts are taken across the range of apertures and zooms (where available), then analyzed for sharpness, distortion and chromatic aberrations. The fastest aperture all three lenses share is f/2.8. At this value, the 35mm f/1.8 and 30mm f/1.4 look much more similar, though there is an unpleasant texture on the bokeh balls of the Sony lens. The 30mm f/2.8 continues to have the smallest bokeh balls but the overall rendering is nearly identical to its two siblings. Sigma 30mm f/1.4 at f/2.8 Sony 35mm f/1.8 at f/2.8 Sigma 30mm f/2.8 at f/2.8 some bad news though; the very centers are sharp as stated above, but the image periphery is very soft, especially at aperturesI’ve gone on many nighttime photo walks and have rarely run into subjects that a bright streetlight combined with this lens couldn’t capture. The Sony 35mm f/1.8 is the only lens that is perfectly compatible with a6300’s PDAF system, which makes sense given that it is a Sony E lens. If you switch over to C-AF and Wide focus area, for example, the green PDAF squares will light up across the frame regardless of where your subject moves. The lens measures 64.8×73.3mm and weighs 265g, which certainly isn’t going to inhibit your ability to carry it around with you all day. It has a 52mm filter thread, and usefully, the lens employs internal focusing, so should you use an ND grad or polarising filter with it, you will not have to worry about the front turning or extending when focusing. Here’s the Sigma 30mm f/1.4 EX DC along with the Canon EF 15mm f/2.8 Fisyeye, and the Canon EF 17-40mm f/4 L lens. Sigma 30mm f/1.4 EX DC Lens In short, each lens seems to have its own set of strong and weak apertures. Despite being the least expensive lens in the trio, the 30mm f/2.8 performs extremely well at its fastest aperture and f/4 at long focus distances close to infinity, while the 30mm f/1.4 shines at closer focus distances, even at f/1.4 and f/2. The 35mm f/1.8 appears to be a good all-rounder, performing well at both close and long focus distances at the centre. Its only downfall is corner softness at the fastest values. Bokeh

the same as Sony's SSM, or in-the-lens focusing motor. As a result of this omission, the Sony version is about 3.5oz (100g) At their respective fastest apertures, the results appear almost identical even though the 35mm f/1.8 and 30mm f/1.4 have a much faster maximum aperture than the 30mm f/2.8. Color fringing towards the edges and corners is fairly minimal and auto corrections are available in current and recent Canon and Nikon DSLRs. At a long distance set to their fastest respective apertures, we can see that the 30mm f/2.8 is sharper than either the 30mm f/1.4 or the 35mm f/1.8. This doesn’t come as a surprise: peak sharpness on an f/1.4 or f/1.8 prime lens is rarely found at the fastest aperture and the f/2.8 aperture of the Sigma 30mm Art gives more contrast to start with. The 35mm f/1.8 is only a little sharper than the 30mm f/1.4 but once again, this is due to the difference in aperture.

The quality of the photos (and the composition of many) was great. I enjoyed this review very much... but I won't get this soon, as I have the Sony 35mm F1.8, which works well with my A6000 because it has OSS built in. by stopping down past F/2.8-F/4, though things still look sharp at F/11, then F/16 softens due to diffraction. Here's After its success with the other five mounts that this lens is available for, Sigma announced in April 2023 that it would also becoming to the Nikon Z mount. Alongside it, the company also introduced the 16mm F1.4 DC DN C and 56mm F1.4 DC DN C lenses for Z mount. Amy Davies has spent some time with each of the new lenses to see how they compare with other mount options.

The lenses in the Sigma trio (again, the 16mm, 30mm, 56mm) are known as being the sharpest lenses in the Sony APS-C lineup, and the Sigma 30mm F1.4 is absolutely no exception. Wide Open Sharpest at f/4 on the A6000, the Sony 30mm f/1.4 DN achieves almost 80% acutance in the center of the fram,e dropping to around 70% in the outer field With sigma 1/50 1/60 is your minimum speed you can handheld with a lot of risk. I have the Sony 35mm. Risk starts after 1/15 shutter speeds.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 An experienced lens manufacturer offering a diverse range of interchangeable lenses, SIGMA provides the innovative Mount Conversion Service, in which we change the mount of a lens in one of our new product lines to another mount of your choice (charges apply).

Thus, I stumbled upon the Sigma 30mm F1.4!

The Sigma 30mm F1.4 certainly met that criteria, weighing a reasonable 9.03oz (226g) and measuring a length of 2.9 inches (7.3cm). I took a few hundred photos with the two versions of the Sigma 30mm f/1.4 EX DC lens, and here are a some photos that help illustrate what this lens is capable of. Sharpness is amazing, but how does the lens handle optical flaws such as vignette, distortion, CA, and flaring? Chromatic Aberrations Despite fairly heavy (–1.7EV) corner shading at f/1.4, close down 1 stop and vignetting on the Sigma 30mm f/1.4 DN is comparable to the Zeiss 32mm f/1.8 and better than the Sony E 35mm f/1.8I have the Touit 32 and I also have a Sigma 30/2.8 which is nowhere near as good. I find it surprising that a faster lens (which usually requires more optical compromise) would be better. But I didn't say it wasn't, just that I doubted it. Here are several comparison images illustrating what different aperture’s produce using the same scene.

When stopped down, this lens is SHARP. Indeed, with an aperture rating of f/1.4, this lens is about four f/stops faster than Canon’s 15-45mm kit lens, when used at the latter’s 30mm focal length. You’ll also be far more able to freeze action under dull lighting conditions, without the need to really push your camera’s ISO setting. The 16mm, 30mm and 56mm F1.4 DC DN | Contemporary lenses are the perfect trio if you own a crop sensor mirrorless camera. These are great lenses for street photography and excel in low light conditions."
