Canon EF 85mm f/1.2L II USM was always one of my favorite lens used on Canon 1Dx.
It was always perfectly focusing even wide open at F1.2 and providing very nice rendering.
Last year I started using A7S for low light shooting (as walk around camera) instead of 1DX and I was never disappointed as A7S was always providing better high ISO image quality at low light conditions compared to Canon 1Dx and also A7S is much more convenient as walk around camera.
Few days back decided to test EF 85mm f/1.2L II USM on Sony a7S and see what would be result of that combo, especially using EF 85 wide open at very low light conditions.
First of all EF 85mm f/1.2L II USM focusing well with Metabone adaptor , though not very fast – for autofocus speed this combo definitely cannot compete with this lens on 1DX.
On the other hand, manual focus using this lens on A7 cameras is extremely easy and always precise (perfect) due to focus peaking feature on A7. As result, using Canon lens in manual focus is much more convenient and much easier than on any Canon camera. Especially easy and precise when using EF85 due to very shallow DOF at F1.2.
Below are some test results for those who might be interested
First two photos are done at extremely low light condition , the rest at normal light.
