In a direct comparison with the Sigma 35mm 1.2 Art DG DN we obviously get bigger circles with the Sigma lens ( = more subject separation due to it being a faster f/1.2 lens) in the center and the midframe areas whereas in the corners the difference is smaller. Sony FE 85mm 1.4 GM and Sony FE 24mm 1.4 GM) and also the Sony FE 35mm 1.4 shows a decent performance. In the past some of the Sony GM lenses have shown an above average performance in this category (e.g. Focus breathing might have an effect at these distances. I did shoot both lenses side by side, they were set to the tipping point between 0.3 and 0.4 m on the digital distance scale to get the same focus distance on both lenses. So in the following comparison we move from the center (left) to the extreme corner (right) and see how the shape of the light circle changes. In the center of the frame almost every lens will render a perfect circle, but only lenses with very low optical vignetting will keep this shape in the corners. Without going too much into technical details optical vignetting leads to the truncation of light circles towards the borders of the frame. optical vignettingįast lenses usually show a noticeable amount of optical vignetting. It is recommended to have a look at this article first to get an idea how this brightness graph works. Vignetting light falloffĪt shared apertures these values are comparable to the Sony FE 35mm 1.4 ZA, stopped down the Sigma 35mm 1.2 Art DG DN shows about half a stop less corner shading. The Sony FE 35mm 1.4 GM is significantly smaller than the half-a-stop-faster Sigma 35mm 1.2 Art DG DN whereas the optically inferior Voigtlander 35mm 1.2 is still noticeably smaller.
Sony FE 35mm 1.4 GM, Sigma 35mm 1.2 Art DG DN, Voigtlander VM 35mm 1.2 III Furthermore there is also a button which you have to press to remove the hood, which is usually only found on higher grade tele lenses. The hood also features higher than usual build quality with a rubberized front bumper and felt on the inside to counteract stray light. The outer casing seems to be made from a high quality polycarbonate and all markings are engraved and filled with paint. On the left side of the lens there is a programmable button and an AF-MF switch. You can also set the ring to “A”(utomatic) and let the camera choose the aperture value or use the camera dial to change the aperture value when it is set to “A”.Ĭompared to the Sony FE 85mm 1.4 GM the click stops are more distinct, especially the “A” setting. The aperture ring has 1/3 of a stop click stops (which you can declick by using a lever on the lens) and those are more distinct compared to the FE 35mm 1.4 ZA. When you turn your camera off the lens will remember the last focus position and will still be there when you turn the camera on again. It takes 180° from the minimum focus distance (0.25 m) to infinity. The rubberized focus ring has decent damping and works better for me than those of the ZA lenses, especially as it does not matter how fast you turn the focusing ring but only how far.

In short: we are getting all the GM goodness (declickable aperture ring, AF-MF switch, focus hold button, linear manual focus) but also some improvements over earlier GM lenses like the Sony FE 85mm 1.4 GM.
