![]() ![]() The camera was set on a tripod (Gitzo series 4 with Arca Swiss P0 ballhead) and 5sec self release had been used. We are looking at the following parts of the frame: positions of crops in the frame ![]() Stopped down to f/2.8 or further the differences between these 3 lenses are within the margin of error. The Sigma 40mm 1.4 Art has the least vignetting at maximum aperture, but the difference compared to the 35mm isn’t exactly huge. Despite the size of these lenses the light falloff is very obvious wide open, but still slightly better compared to smaller fast lenses like the 40mm 1.2 from Voigtlander. These values are for the extreme corners of the A7rII. The 40mm 1.4 is certainly the worst, not only is it the heaviest but weight distribution is also worse compared to the 35mm 1.2. Hood design is the same as that of the 40mm.Īll of these are big and heavy lenses, but the 35mm 1.4 certainly is a bit easier to handle than the other two due to smaller size and less weight. The 35mm 1.2 is a focus by wire design (without distance scale) and in addition to the AF/MF switch it features a de-clickable aperture ring and a focus hold button, just like the Sony GM lenses. The only noticeable difference is the lens hood: the 35mm 1.4’s is just a simple piece of plastic, the 40mm 1.4’s features a release button and is made from a mix of polycarbonate and rubber. ![]() They both share an AF/MF switch on the lens, too. The 35mm 1.4 Art and 40mm 1.4 Art are very similar, they both have a mechanical coupling between focus ring and internal mechanics and a physical distance scale, very rare among “native” E-mount lenses. Sigma 40mm 1.4 Art, $1399/1150€, | | B&H | | (affiliate links) Build quality/Handlingīeing from the same manufacturer there are many similarities, so I will mainly talk about the differences. This is how the field of view compares: Sigma 35mm 1.4 -> Sigma 35mm 1.2 -> Sigma 40mm 1.4 (from bigger to smaller) The 35mm 1.2 is slightly less wide than the 35mm 1.4. The 40mm 1.4 was kindly provided by a reader, the other two lenses I bought myself. The influence on other aspects like bokeh and color correction are usually less affected by this though. The Sigma 35mm 1.4 Art for example works generally better in combination with my A7III.įurthermore no lens is perfectly symmetrical, so it is possible I picked the best corner of one lens while I picked the worst of another. As lens and camera tolerances (sample variation) come into play, it is possible that a certain combination of lens and camera shown here may perform above or below average in certain areas, like off-center sharpness or field curvature. Disclaimer: I only tested one sample of each lens on only one camera. ![]()
