I am looking to start shooting medium format. I shoot digital and 35mm and would like to venture into the larger frame stuff. I have been looking around and am about 90% certain that it will be a TLR. Portability is key. I am not interested in something that requires a tripod 100% of the time. If I am doing landscapes, tripod is no big deal. If I am walking around, I would not mind being able to just shoot. The other advantage of the TLR is the ease at which I can take a waist level photo (less obvious than shoving a camera in my face and pointing it at someone). Am I unfairly missing anything before I shell out my money?
