Unlike others, a little practice (even with a standard screen) and manual focusing is not that difficult, I probably spend as much time focusing as I do just twisting a zoom ring. I probably get more keepers only because I can't "spray and pray" with AF in play...take a bit more time, wait, snap.
I'm fine with focusing manually but have to admit it's a lot easier on my Zeiss Ikon than the Canon 5D because of the viewfinder. I have never been much for zoom lenses, got rid of all of them and sticks to primes only now. I couldn't be happier
Oh, the 50 1.4 and 85 1.4 are the "entry level" lenses - the 35 if I remember is a few hundred more IIRC.
I'm not that interested in a 85mm focal, usually don't need longer than 50mm and I got the 135L just in case. I decided to skip the Zeiss 50/1.4 because I have heard many mixed reviews on this lens with focus shift and such. From the current Zeiss lineup it seems that the 35/2 is the best one to start with if you don't want wider than 35mm or macro.
