Loaning out your precious DSLR to a friend who doesn't know shutter from aperture? Got a classroom full of trainee photographers whose lesson requires they be set to a particular mode? Canon's hoping you'll drop an extra $129 on a version of the critically-acclaimed EOS 7D that lets you control how your lackeys fire off shots. The $1,829 EOS 7D Studio Version adds four tiers of password-protected locking controls, plus an optional barcode and data transfer kit (to organize and commit large photo sessions to databases) using a custom version of the company's WFT-E5A wireless transmitter for just $770 m
