I have two 35/2.8 lenses, each of which has its virtues.
The first is an early-70's version of the 35/2.8 PC, with the collar milled so it clears an AI tab. This is, simply, one of my favorite lenses. Aside from the usefulness of the shifting, it just seems to do its job well, sharp and with colors that look right. Some of that may be gearhead placebo effect, as I find it such a beautiful machine. On Photo.net there's a "fixed focal length friday" thread, and I usually go out on a thursday with this lens and grab whatever looks nice that day. The first shot was made in December, of Neshobe Island on Lake Bomoseen in Vermont.
The second, bought some time ago for nearly nothing, is a 35/2.8K, milled to AI. When I got this I found it pretty blah on full frame, not bad but not great. On DX it comes into its own, decently sharp, easy to focus, tough as nails. The second shot is one I just took in the back yard. I like the PC lens so much I rarely use this one except when traveling. (edit to add: both these are taken with a D7100)
