Hello, I have a full set Bronica ETRs body + 3 lenses + waist lever + pentaprism + 120 backs + polaroid back + bellows + accs. Pay good price for the set but really do not use certain accessories. Perhaps with the 75mm lens and to a lesser measure the 50mm would cover my needs. A TLR might be a good option with fixed optics (mecanical vs electronic) . My main fear is if electronics can cause problems. Can anyone tell me if this particular model is usually to electronic problems or if has any weak point ?. If so, has easy repair ? . Always keep the equipment in good storage conditions, and I use it regularly. A greeting and thanks.
