K-7, and Nikon has done the same on its D3S, but none of that really matters if you're the proud owner of a Canon, now does it? For those fed up with accidentally moving their mode dial during a critical shoot, Canon is now offering a chargeable service for the EOS 5D Mark II and EOS 7D cameras. For the tidy sum of $100, the outfit will install a Mode Dial with a center-located lock button -- the goal here is to prevent the wheel from moving during "normal camera operation," while simultaneously milking an extra Benjamin out of the outfit's loyal customer base. 'Course, there's a glass half-full / half-empty way to look at this. You could bang on Canon for not including this from day one, or you could be grateful to have the option at all. Your move, cynic.
