No need for another zoom. Love it! (Except when you need AF)

Well, I gave my Contax N 24-85 a whirl today on the A7r...it's a Conurus conversion for Canon EOS. On the 5D2, the AF works like a charm. On the A7r, the AF is pretty much useless (I'm using a Commlite adapter, which seems to work very well with Canon EF lenses on the A7r). The AF never locks on...it hits the spot, then continues to hunt. Taking the lens out of AF mode and using MF, the results are as expected. I'm not much of an AF guy, but once in a while it does come in handy. The other oddity is that since the camera detects that it is an AF lens, I'm not able to use the AF/MF button to zoom in for critical manual focusing (unless there's another way to do so?), even when the lens is taken out of AF mode. I do have a non-AF adapter in EOS mount, so it looks like that will have to do for this lens.
