Okay, so my all-time favorite lens (and focal length, on film) is the Leica 35mm Summilux-M ASPH. But I don't shoot 135 film anymore, and this lens is nice on an M8 but I don't own one.
I found the Leica pretty remarkable, in terms of color and pop/3D look and sharpness wide open of course.
I'm a Canon guy, currently, and looking at moving from a 1DMkII to full frame, in the form of a 5D or a 1DsII (or if they get the lead out and release a 5DII, probably that).
Canon's 35mm f/1.4L is reckoned to be a fairly wonderful lens.
But I'm also thinking of the D700 (see above re: hurry up, Canon!). Nikon doesn't have a 'special' fast 35, but there is the Zeiss ZF 35mm f/2.
Now, given that my on-the-camera-most-of-the-time lens will be the 35, and assuming you believe in such a thing as "special lenses", I'd love to read a discussion of the relative merits of the three lenses noted. So, questions:
1) Is there anyone who's used all three? Which was your favorite? Why? Second favorite?
2) If the ZF35 is really nice, is it enough nicer than the 35L to warrant using manual focus? Or should I just suck it up, use the 35L on a 5D and bide my time until the 5D is replaced with something comparable to the D700?
