I wonder if anyone has had this happen before, and if so what was the cause before I ship the camera off to CPS at Elstree for repairs.

As soon as you switch the camera on it starts taking images. Neither of the shutter button appear stuck down or any other obvious problems. The shutters still working and continues to take images on to the card, but the only way to stop it is to physically turn the off switch on the back.

The camera is due a service anyway and probably getting near to its shutter life but the shutter does'nt seem to be at fault.

Have removed and re-inserted the main battery but no change. Have not taken out the backup battery though

Any ideas please :thinking:
 
Even though you say so my first thought would be shutter button stuck, so would press both down hard to release them if they're slanted

Also to troubleshoot if it is a button problem try turning off the second shutter and try it again?

Other than that, yeh would send it off

Many thanks, tried isolating by turning off lower button but still keeps firing and the buttons appear ok, think its going to be off for a trip down the M1.
 
id put my dosh on the shutter button it is prob broken
 
Thanks Rab, probably agree but never had any issues with the buttons with any previous Canon cameras and I've had a few over the years.

Maybe there's a first time.
