Nice thread! I don't own a digital camera. Not out of choice so much. I am just spoiled by the huge, beautiful images you get from shooting MF with good glass. A lot of the prosumer (read: what I could afford) DSLRs feel like toys to me. Thinking very hard about a K20d though. I could use all my 35mm lenses, which is a huge + for me. Digital photography is just not in the cards for me right now, but I'm not afraid of technology. Also, anyone who shoots MF knows the warm fuzzy the aesthetic of film gives you. I feel like shooting film is more of a discipline as well blah blah blah...
I use a 67II, Mamiya C220, and a beat up old K1000 for 35mm.
I shoot the same 2 films almost always. Ilford HP5 for B&W or Velvia 50 for color. Shooting color very rarely these days, but Velvia 50 makes for a nice photo when exposed correctly. If I'm in broad daylight, I'll shoot Delta 100. I have used Tmax here and there, but I prefer the warmer tones of Ilford's films. I also like that Kodak C41 process B&W film, but no one seems to carry it locally anymore.
For 35mm, I shoot Delta 100, Velvia 100, or HP5.
