Summary: Can confirm that it works with the A7s with the LA-EA4 Adapter. Full autofocus. It makes the same noise when autofocusing that it did when it was a film camera lens. It's as sharp as anything I would expect at this price point.
Summary: The auto focus is very slow and barely work in cold weather. Even when it does work, it is not very accurate and I get a lot of blurry photos. I can manually focus it faster and more accurately than it can auto focus, and I am not particularly fast or accurate.
Summary: An amazing lens, this packs every focal length you could need into one solid lens. I've used it for photojournalism and have produced some outstanding images. Sharpness is really good, AF speed is solid, and the lens is very compact when walking around.
