Hello from Sweden and thank you for adding me! My interest is macro photography of ornamental shrimp in aquarium. These are about 1" long and I use my Fuji X pro-2 with a 1,4 teleconverter plus an 11mm extension ring. That combination gives me a 84mm macro lens that works for me. To freeze these little shrimp I use studio flash from above and beside the lens. Settings are ISO 100-200, 250/sec. f10-8 and that works for me. But I like to step up to a bigger format for more details and tonality. Would a medium format like H3Dii-31 with a 120mm f4,0 macro give a rather big jump in quality of detail, colours and sharpness?
