Today I tested my new Canon 5DSR - with 50 megapixels it's pretty close to medium format. The detail is pretty amazing and super sharp.
These were taken in JPEG mode, so you can imagine what RAW is capable of. For lights I broke out my Profoto D1 500's with a 2x2 soft box and a 20 degree gridded reflector.
