All my SLR's are film - tried to like digital, but my whole picture-making thought process revolves around film, so gave up the effort.  Since I collect and use old film SLR's, I have Nikon, Pentax, and Canon.  No AF or motor drives (some meters don't even work), just the basic stuff that I'm most comfortable with.  Currently using Pentax and P-type screw mount bodies with 28, 35, 50 or 55, and 70-210 glass, plus my always-in-the-bag Gosen Luna-6 Pro meter.  Use CN film (usually 400 speed) and have it processed and burned to a CD, which I print from at home.  Makes beautiful b&w's in PhotoShop!
