It is long thread to read now, so i will read it later another time, i also interested to do some closeups and production photography but the problem will be the sharpness and the DOF and colors to get accurate as final result, i was not sure if i can use 35mm digital or MF or go for view camera, i saw many Jewelry and watches shots that i like but i don't know what they did use and how.
Once i was in Hasselblad and Profoto event in my area and they were presenting H4D-50MS [or maybe H3DII-50MS] and the results were amazing as details and sharpness, but i forgot which lens also didn't see how many lights was used.
