Good Evening- I just bought a Bronica SQ-Ai in minty condition with the intention of using it for landscape photography. I would appreciate any suggestions that folks here may have regarding how to get the most out of this camera if I intend to convert negs to high res scans and post process digitally. I am particularly interested in suggestions for film (both color and B&W), processing labs and scanning. I also would appreciate information concerning the best sources for lenses, backs and screens. I am familiar with KEH, B&H and Adorama. Are there any others? The camera comes with the standard 80mm lens and I would like to add a 40mm or 50mm. Many thanks.
