Canon EOS-1D Mark III, f/8 @ 100 mm, 1/200, ISO 100
This shot was taken using the Zeiss 100mm f/2 Makro Planar. The detail when view up-close is incredible. The shot is worth clicking on and seeing full size - it is a 100% crop.
Here is the lighting setup. Just out of frame on camera right was a reflector to soften shadows on the right hand side. Basically a studio flash with gridded dish on subject left. Black cloth background also draped over a table with a clamp holding the flower.
