Any long time user of this lens. Do you like this old lens or not. Thinking about buying the 135 f2 for $750.00 USD. It's in real good shape,but not in mint cont. I'll be using it wide open most of the time. My 85 1.4 Isn't long enough for what I do and alway end up using my 2oomm 3.5 which is too long and slow. ( candids/indoor sports). I use an old AE 28 f2 which is my main lens. That's a great lens and I'm hoping that the 135 f2 is the same. Thanks Joseph M.
