Canon seem to have a major problem with the shutter on the 40D camera. I know of six users that have the same problem, three of them have sent the camera back for a fix, but the problem still remains.
Mine has started to show the same symptoms, the shutter sticks open. The only way to release it is to take another shot and hope! So far that has worked but long term this could be a major problem.
I wondered if any users here have noticed anything?

I had been looking at getting the 40D until I read about the problems you mention........and not just here!! Not impressed with Canon at the moment.........will stick with my Sony dslr at the mo............and use the compact Canon I have.

Good luck with it mate........really.

Funny that, I was stopped by a photographer in the street who noticed my gear, he wanted to ask me what setting stopped the shutter staying open on his 40d.
I think you may be right !

Are you sure you havent got MLU selected, if as you say Canon had a major problem then I am sure it would be widespread knowledge by now Wink

I have to say this is the first time I have heard of them as well - Mirror Lock-Up does sound very similar to what the original 3 are describing. Resetting the camera to factory settings would disable that setting - although reading the manual would also let one know how to turn it on and off.
If this were a widespread problem I am sure I would have heard of it by now

edit - or Bulb mode - which would hole the shutter open rather than holding the mirror up - you could tell because the bulb mode lockup would mean you got overexposed shots whilst mirror lock up would just lock the viewing mirror up - the shutter would remain closed till the second pressing of the shutter

it does sound like mirror lockup.
I have 40D and haven't got the problem.

Quite certain. The fault is very infrequent on mine so far. I can go for days taking over 1,000 shots without it showing, only for it to happen again the next day. Yesterday it happened during a continuous shot burst, the camera acted like the buffer was full, stopping after only four shots had been taken, then to start again perfectly OK for the next 10 shots. I know it's a sticking shutter fault as I'm left with a shot that's almost pure white. It's simply not reproducible on demand so I'm not yet prepared to send it back to Canon.
The fact I know of 6 users that have this similar fault surely points to it being a more widespread problem. I don't know that many photographers to make that normal!

Its not the hallmarks of shutter death approaching by any chance? I know that death by shutter failure is something that is not openly mentioned when on looks for a new DSLR (the idea that its got a limited lifespan). Could it be that you - or some of your 6 associates - have got near to the shutters estimated limit for shutter acuations?

that would be some seriously heavy usage for a camera that should be good for 100 grand actuations.........

give me 250 days in a zoo and I could get 100,000 shots Smile

Sounds like a firmware problem. Not seen it on mine.

Mine has done 11,500 odd shots.(Very odd!) Hardly at the end of it's rated life just yet!
