When I started out, I shot mostly landscapes at 18mm (28mm equivalent) on my K100D. Now, I'm shooting landscapes, street photos, abstracts, and pretty much anything else that catches my eye at 50mm (on 35mm cameras, so it's a "true" 50mm. 50 on digital would be way too long). I have a telephoto that got thrown in with one of my cameras, but I have yet to shoot a frame with it. As far as I am concerned, 50mm (or equivalent) is the perfect focal length for my "everyday" shooting, to the extent that I think the reason that I don't shoot digital much these days is that I hate my slow kit zooms and the viewfinder just doesn't focus well. I guess I'm spoiled by my Ricoh's split-image finder. I've been looking to try shooting some portraits, since it's A) been sorely neglected in my photographic development this far and B) seems like more or less the only way anyone ever gets paid doing this. I'll probably end up splitting time between my 18-55mm at 55mm (f/5.6 ugh) and my 50mm f/2 manual K-mount lens (can you say "hit-or-miss?"). Actually, come to think of it, my 50-200mm is faster around 50mm than my 18-55mm, not that that's saying much. So, that rant notwithstanding, what is your favorite portrait focal length?
