Last week I mentioned on my blog news feed that Canon released a product advisory notice announcing the availability of locking mode dial modification for 5D Mark II and 7D camera bodies. As of December 6 (2010), 5D Mark II and 7D owners can send in their cameras to Canon if they want this modification. The cost is $100 USD for US customers.
The reasoning behind this factory modification is due to the fact that some 5D Mark II and 7D owners have had issues with the mode dial getting moved inadvertently from one mode to another mode. Typically this happens when the operator has the camera on a strap and slung over the shoulder or around the neck and the camera’s mode dial gets bumped against the body or another object (e.g camera bag).
Quite often, I’ll be using my camera with a Black Rapid RS-4 camera strap. I’ll be taking some portraits and then put the camera at slung at rest (against my side). Then the body rubs against the side of my body and the mode dial gets moved from my expected setting (typically Manual or C3) to another setting (e.g. Bulb or Shutter Priority). Then when I bring the camera up to my eye to take another shot, I’ll end up taking a photograph in a mode with settings I didn’t expect (and aren’t correct for the situation).
Thus, when Canon announced this, I was very eager to get the modification on at least one of my cameras (I currently own both the 5D Mark II and 7D), even at the $100 cost.
So last Tuesday, I drove out to the Canon Service Center in Irvine (California) just before they closed for the evening and dropped off the 5D Mark II. The next day (Wednesday) I received an email notice that the service was complete and it shipped out. Then on Thursday I received it via FedEx. Basically a 2-day turn around time. Very quick. I was expecting a full week. Though, I am a member of Canon Professional Services. So that may have had some impact on the turnaround time since CPS members get priority service.
Anyway, the dial looks like a normal dial except the center of it has a spring loaded button that must be depressed (down) in order to rotate mode dial.
The mode dial is simple to manipulate. Instinctively, I’m pressing down the center button with my index finger and rotating with the thumb (and middle finger if more torque/grip needed). It appears possible to manipulate it by just pressing the center release button with the index finger and then sort of ‘gripping’ the mode dial face with the pad of the same index finger.
But the key point is that the mode dial doesn’t move unless the center release button is depressed while rotating.
A photographer friend of mine asked me if the mode dial modification is worth it.
Well, $100 USD is a bit pricey for a simple modification. But Canon not only did the modification (parts and labor), they also cleaned the camera (sensor, viewfinder) and shipped it back to me for no extra cost. I believe cleanings are around $60 if done by the Canon Service Center. If that is true, then the $100 cost doesn’t seem so high.
The answer to the “Is it worth it?” question is more a personal preference. If you have ever lost capturing that special moment because your mode dial got inadvertently bumped to another setting, then perhaps $100 is a small price to pay to never again lose the moment because of a bumped mode dial.
