Hello all! I've been looking recently into medium format hardware, as I've been shooting 35mm consistently for the past 8 years or so, and I'm looking for some opinions on equipment. Right now I'm debating between the Bronica ETR-Si and the Bronica SQ-A. From the information I've gotten, shooting the SQ-A with 6x6 will yield better quality than the ETR-Si with 6x4.5... is this incorrect? I am looking for a substantial image quality improvement with the switch to medium format, and I've been told that that can be accomplished, but that 6x6 is better. The ETR-Si seems a bit more affordable, and equipment seems to be more plentiful, as I haven't found much in the way of add-on equipment for the SQ-A (finders, grips, lenses, backs, etc.). Anyone having any opinion on this, please do chime in. Cheers!
