Curt: Not in my experience. I often shoot corporate images at f/5.6 with adequate DOF, especially using a 35mm focal length lens. Plus when you are shooting computer screens at F/11, the shutter speeds a very slow and awkward, especially with models sitting in dark, etc. The T/S Canon lenses would be wonderful for corporate stuff because the TS could help cut DOF needs, and thus the necessary strobe power. I not uncommonly use 6,000 to 10,000 WS of strobe when shooting with 67 to get f/11. With 35mm, i can often reduce that to 2,000 ws total. One of my studio partners the other day was even exclaiming about the difference in DOF between his Hassy and Pentax 67 systems (an 80 versus a 90 for normal). The Hassy was significantly easier to get what he needed in focus. The other alternative is to make your compositions as much as possible on the same plane for minimum DOF needs, but that is usually boring. Donal Philby San Diego
