I have already a Pentax 6x7 for landscape and Bronoca ETRs-I for portraits. My Nikon F3 and FM are my backups. I like both specially for street photographs, but I think I have too many cameras and lenses and I would like to have something to replace them which I still could continuous with my street shots and travel. So I was wondering about change them for a twin lens camera (6x6). It is doesn't need to much space to store and carry in the streets and travels, nicer size negatives and I can use as my main camera for portraits and studio shots while I have my bronica as backup. Whay Am I saying it here??? Because I want to hear from others if they think I could miss some possible benefices from 35mm I could be forgetting now. A part from the fact that I will shoot less since I will have less frames per negatives. But is there anything else I could regret?
