Sigma 33B965 30 mm F1.4 DC DC Sony E-Mount-Black

Product Information

full frame 35mm type camera, and is an attempt by Sigma to capture a market share in this focal length and speed that Sony As is the way with modern lens design, the 30mm f/1.4 shows visible barrel distortion when looking at uncorrected raw files. Sigma advises Sony users to set distortion correction to Auto, which should fix this in the camera’s JPEGs. Micro Four Thirds cameras will always correct this automatically. Sigma 30mm f/1.4 DC DN C X-Mount on Fujifilm X-S10

The Sigma is capable of delivering richly detailed images with impressive sharpness and contrast, along with fairly minimal distortion (Image credit: Matthew Richards) up when the sun is close to the image, about the same as other lenses with this basic focal length. In the box you'll

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) The lenstip resolution record you refer to is in regards to the four-thirds system. That is to say, it is the sharpest lens they have tested on the four-thirds system. So, without them also testing the lens on a larger APS-C sensor, we can not conclude that lenstip would have arrived at the same conclusion for APS-C.

I have briefly tested the setup with Canon's legendary FD 35-105mm, Macro (not an L lens, but well known for its sharpness and great optics). With the Sigma 30mm f/1.4, the PDAF squares only work across the vertical central area of the field of view. If the subject moves outside of this area, the camera will use contrast detection AF instead. Our hope is that the lens will become fully compatible with PDAF via firmware update at some point. 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 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.There obviously isn’t much point in an f/1.4 aperture if you have horrible hexagonal bokeh, so sensibly Sigma has employed nine rounded aperture blades to ensure that when the lens is stopped down to f/1.8 and beyond, the out-of-focus areas show nice circular specular highlights and smooth transitions. All three lenses make room for a fly-by-wire focus ring on the barrel. Those of the 35mm and 30mm f/1.4 are ribbed while the 30mm f/2.8’s is perfectly smooth. We find the 30mm f/1.4’s the most pleasant to use, partly because the deep ridges make it easy to turn but also because it is made of rubber, which prevents it from becoming uncomfortably cold in low temperatures. However, the 35mm f/1.8 is the easiest lens to unmount because its focus ring takes up less space on the barrel than either of the other lenses.
