To confirm. I have an original canon lens and aftermarket tamron and the camera offers the same problems with either lenses.

Can you take pictures without issues when the lens is set to MF? Have you checked the memory card, to be sure its' good?

Double check the internal menu settings. Check the owner's manual on how to reset the camera.

Have you tried a different battery?

No, it has the same issues be it on AF or MF. I have changed the memory card and also done a standard clear settings reset. I do not have access to the manual so not sure how to do a hard reset or if this is even possible.
Please note it takes a picture on start up and often when you are turning the dial between different settings. Any additional ideas would be much appreciated if ya have any?

I have changed the battery, I have two for travel purposes and it posed no change at all. Thanks

You can download a manual. Google Canon manual for 550D.

You have to change the 'Drive Mode', as suggested above you need to downloaed the manual.

I have changed the drive mode in hope of using the two second feature, at least this way it could still take pictures. However it still has the same issue.....

What is camera doing? Is the red "busy" light lit up? Does it show the shot image on the LCD before it hangs? Does everything else work, except for taking a shot? Does it download image files?

When you turn it on, it takes a picture and then will focus on objects and you can hear the beep saying it has focus, it just won't fire from there.
After having a go at changing the drive mode, I also put it into live shooting mode and for some reason this actually got it going again and i could take shots again, even after switching it out of live mode. Unfortunately that did not last and now I'm back to where I begun.
Takes a picture on start up and often when you turn the dial between shooting modes. Everything else seems to work fine, the pictures I took whilst it worked were good. It just won't do it consistently...
Any ideas?

Are you using One Shot Focus? Try using AI Servo, the one that doesn't beep. What happens?

We assume that you have sufficient light and distance from the subject to properly focus and take a picture.

Sorry for the late reply, I've been without out internet connection for a few days. I have tried to use the AI Servo setting and get the same result.
I have two different lenses and tried them both in the initial trouble shooting stage and in various scenarios, all with the same results.
I'm no professional but I believe there is some kind of short circuit between the trigger button and the main shooting mechanism. Because it seems strange that by clicking it to live view, I managed to get it going for a short while again.....
Any more ideas are greatly appreciated.
Thanks

Have you tried firing the shutter with a remote IR trigger? (I just looked at my wife's T2i, and it does appear to have an IR receiver.) If that works, it probably says that the shutter button is sticking or that something's broken in the mechanism. If I understand your description of the symptoms, the camera fires when you turn it on, whether you push the button or not. I guess that's at least consistent with a stuck button.

I haven't actually tried that, seems a good idea but where would I get a remote IR? It doesn't have a Wi-Fi connection so it would involve purchasing one wouldn't it, or finding a camera shop in South America that would let me try it first.
Yea it fires on start up, every time and sometimes when I switch the dial between modes, and then sometimes when you put it on to live mode.

IR triggers aren't very expensive, and it's useful to have one if you ever find yourself needing to take a selfie. Or if you're using a tripod and don't want to risk jarring the camera with your finger. B&H has a presence in Brasil, I believe; maybe you could order one from them.

Of course if a stuck or broken shutter button is the problem, you still have to worry about whether it's worth getting it fixed. But even if you don't, the IR trigger will probably work with your next camera.

Hello. I’m only replying to this thread after seven years. I’ve had a similar case with a 5D III two days ago and I have been searching the net for a solution. This is the first case that looks like mine. The camera also takes a shot when I turn it on. I can actually take a shot after having pressed a button like menu or playback, only the camera immediately takes a shot, no half press. The menu, playback and start/stop buttons don’t respond unless I half press the shutter. This is my weird case. Have you finally found a solution to yours?

Please start a new thread for your issue. Thanks, ahead of time.
