Ok, I've ignored this issue for a few days wondering if it was really really isolated, and after a few days, more than a couple have reported this, so in order to investigate the issue, I'm reporting it. I don't think it is something to start a panic over, but it seems that it should at least be exposed to a wide audience to see if there are hidden cases that aren't being reported.
Have a tip, a video, or a Canon 5D2 product to announce? Give us a shout
Several days ago, posts on twitter and a post on the Photography Show blog (by Gavin Seim) appeared asking if anyone had an incident where their lens had fallen off of a Canon 5D mk ii. Here's a quote from the blog:
“Those who listen to the PPS podcast are aware that I recently sent my brand new 24-70 2.8 L lens to Canon for repair because it fell off my 5D MK2. I love my MK2, but I was on the dance floor at a wedding happily shooting away and next thing I know my twelve hundred dollar lens is rolling on the floor. Pretty disconcerting.
Thereâ€™s was that chilling intake of breath from the crowd, that most of us who have publicly dropped a piece of gear are all to familiar with. Like any pro, I kicked the lens off the dance floor with disdain, while casually saying. â€œHeck that old thing. I have a whole case of them in the carâ€. OK seriously though, I kept cool and finished the wedding just fine. If you want to hear about that listen to PPS podcast #58.
Naturally Canon treated the situation as if Iâ€™d dropped the lens outright and the the repair cost me about $200. Not a huge deal. I figured perhaps I somehow hit the release button. Then I got to thinking. Should that happen since you we you have to to rotate a lens with some pressure to take it off. Probably most people thought I was being clumsy and did something wrong. I was using the camera quite normally however.
I was about to let it go when I found Iâ€™m not the only one this is happening to. Seems that thereâ€™s various reports coming in about lenses falling off the MK2. More all the time. So I decided to write this post to talk about this. Does this happen commonly? How about on other cameras besides the MK2. Do Nikonâ€™s ever have this issue?”
It is a legit concern if people are having a problem and so I'm trying to spread the question. I don't agree with the tone of some of the replies in that blog (read the comments)… some are making it sound like a huge issue and that everyone is having a problem.
The lens mount is a twist mechanism with a lock at the end of the twist. Obviously Canon has been making these for maybe a decade and I can't imagine how there'd be a flaw in the 5D mk ii, but it is possible. After reading some of the posts, I spent a few minutes trying to abuse my 24-105 on my 5D mk ii and I couldn't even force it to come loose with some vigorous shaking. Even pushing in the lens release button and letting it go (without twisting the lens to begin to remove it) would not make the lens come loose. But maybe that does happen in the case of these other users? Has it happened on other Canon bodies?
Sound off over in Gavin's thread (best to keep everything together).
