Last week, Canon announced the locking mode dial modification for the EOS 5D Mark II and the EOS 7D. I immediately jumped at the chance to have this upgrade performed. I needed to send my 7D in for a yearly checkup anyway so the announcement came at an opportune time. One of my biggest complaints about the xxD and xD series of camera bodies has always been the flimsy mode dial. I have owned a 40D and used a 30D briefly when some of my equipment was in the shop. I always had issues with the mode dial switching to another setting while I was carrying it. Why canon chose to put a locking dial on the 60D but left it off of the 7D and 5D Mark II will always be a mystery. In my opinion this is a design flaw with both of those camera bodies. The forums are pretty divided about whether or not this is necessary modification. As a former Nikon shooter its nice to have this feature again. Nikon uses a locking mode dial on almost all of their cameras-Canon take note. There isn’t much else to say about the modification. It functions as advertised and prevents the dial from being turned inadvertently. The modification isn’t cheap (at $100) but the cost of missing a picture because the mode dial was accidentally switched to another setting is a much greater cost to me. Overall I recommend it.
