I don't use autofocus much but I was satisfied with its performance on the few occasions when I needed it. It should work very well with your f/2.8 lens. I like my MZ-S a lot. Enough that I grabbed a second one when I found a demo unit at a very attractive price. The motor drive is more than quick enough for everything I've shot but I'm not a sports photographer. I shoot slides exclusively and the metering system is accurate enough that I very seldom need the spot meter. I do recommend the battery grip unless you have access to a cheap and plentiful supply of CR-2s. If you're going to shoot enough film to justify the expense then I recommend the camera. It's a jewel.
