This photography on this website is all shot on Canon equipment. In every case the lens selection is prime verses zoom. Most product type shots use Canon T/S lenses from 24mm T/s, 50mm T/S and 90mm T/S. Lighting used are older Broncolor strobes and natural lighting.
Tripods are by RRS, Ball head from the German company NovoFlex and L-frames from RRS/Arca-Swiss.
Arca-Swiss L-Bracket (at B&H # ARVHLH MFR # 802306). No more "custom" L-Brackets, this thing seems to fit just about anything (Pro body, batt grip, etc.). Heavy, like a tank, but the quick-releases allow adjustability and the L to be pulled right off the base with no tools. Rock solid quality.
