Here's the dilemma: I've moved from 35mm to MF and have loved using a couple of new Rolleiflexes. I love the big negatives, tones, format, etc. Because of this, I sold off one 35mm system and now have some money to spend. Question is: Do I take a dive in 4x5, which I understand is very different from MF, or do I go ahead and delve into digital 35mm and buy a bodythat backs up my film 35mm (and MF to a degree). My forté is portraits, not landscapes.
