I received the 7artisans Canon EF -> Sony FE adapter, which is to replace the old Viltrox Mk III which caused scary electrical freezes of the A7RV body, so I ordered a replacement.

Canon EF 85mm f/1.8, 7artisans adapter, Sony A7II

The new adapter works, I tested it on both A7RV and A7II, with EF 15mm f/2.8 fisheye, EF 85mm f/1.8 and EF 50mm f/1.8 STM. The samples are shot with EF 85mm f/1.8 wide open on A7II. Autofocus works, even on the 85mm, which is surprising since AF on that one failed to work at all on the earlier adapters. It’s glitchy, so “exit and enter again” is a thing, but even continuous AF works on the A7RV, which is unexpected but welcome. Yeah, CA on the 85mm Canon, when shooting into the light, are nasty, but otherwise the lens is creamy and sharp. The 15mm fisheye is sharp enough on the 61MP body at f/8, and the files would produce very nice B1 prints; however, even at f/5.6 and f/11 there is a visible loss of sharpness, and outside those apertures the result is not of prime quality, to put it mildly.
