Also in the new recently is that Canon are offering the locking dial from the EOS 60D for the EOS 7D and EOS 5D-MkII for a small fee of $100. The European/UK price has not been mentioned at the moment.
I’m in two minds about this, I feel that the charge (which will probably be around £100) is quite reasonable for the addition. However, I cannot ever remember ever taking one of my 7D’s out of the camera bag where the mode dial wasn’t where I left it! I have more of a problem of leaving it on of the wrong Cn settings (C1 ,C2 or C3) for the picture I’m taking.
I guess that for some people this might be a problem so they may be interested.
What this measn is that all Canon models from now on (with mode dials) will have a locking function. Roll on the 7D-MkII and 5D-MkIII 🙂
