Put a different memory card in the camera. Do you get the same problem?
Please let me know

It worked OK in the other camera which had another memory card already in it. Are you saying the memory card was at fault?

We are not sure yet Chris, which is why we need to put a different memory card in the camera, take a photo and test so we can either confirm or eliminate this as the cause of the problem.

OK but this will take about half an hour - is that OK?

No problem at all Chris

Just tried swapping everything around and everything seems to be working fine now on both camera bodies.

so when you put the other memory card in it works fine?
Customer: replied 2 years ago.

Seems to work with all the memory cards. Is it possible to send you a shot showing what the photo looked like?

sorry your confusing me here Chris
you just said
"Just tried swapping everything around and everything seems to be working fine now on both camera bodies."
What was swapped then and what is working fine?
Please remember I cannot see what you are doing so please be more detailed in your responses as to what you are doing.

I have two canon 550d camera bodies. The lens is a canon zoom EF-S 17-55mm f2.8 IS USM.

The memory cards are:SanDisk 16GB Extreme

The problem I had on Saturday at a wedding is no longer happening. I am worried though as I do not know why it happened then and if it means there is a problem that could re-occur.

Do you not have an option to send you an example?


Thank you for that Chris.

Two causes for this Chris
1) Something was on the side of the lenses interfering with the picture.
2) The imaging chip is failing.
I think you would have seen something obstructing along side the lenses, so it points to the imaging chip. If it was due to an issue with moisture or heat then it may have been a temporary malfunction, else the chip is becoming defective and may occur again after prolonged use.
To check for this, take 100 photos one after another and if it re-occurs you know its due to a over heating issue and the camera needs to be replaced, else it was an environmental cause and it should be ok.

It was a very hot day with temperatures in London of about 28 degrees centigrade. Perhaps it was a case of overheating.

I will try your suggestion to check. If it is the imaging chip, where is that - in the camera or the lens?

Also, can the imaging chip be replaced by a service engineer or is the whole camera a write off?

The chip is in the camera and if this is the case it is a write off Chris, best to then get the camera replaced.
If you would like any additional information or assistance, please do not hesitate to let me know.
