This is the second time this has happend. Firing away and it suddenly go's dead.

last time I was trying to photograph Woodpeckers on a feeder with a 50/500 lens on continuous firing and suddenly it stopped. This morning it happens again this time with a 15/85 lens, but on single shot

First time I was on holiday and left it when back home I looked through the manual troubleshooting guide. I have tried all the answers ie ( battery not installed properly, recharged the battery, battery compartment cover is closed properly, and card slot cover closed ). I use only Canon batteries and both are fully charged 1 only last night.

Is this a odd problem or a common one that a repairer would be able to fix, or ship to Canon for repair. It is not under guarantee.

Oh dear, sounds a bit unfortunate. Have a chat with these people.     http://camera-repair.co.uk/

I have used them in the past with my Canon. Top class service. They might be able to advise you.

Before you send it away for repair … how old are the batteries, it could be possible that both the batteries are dead and cannot hold their charge … try changing the clock battery, having just done a quick google search it seems that a near dead clock battery can do some screwy things in some instances.
If possible try resetting the camera back to the factory settings. Again if possible try updating the firmware; the latest version is 2.0.3 … if you are using the latest firmware update, try refreshing it by over writing it.
Do you have a battery grip connected; try using double A batteries with the supplied magazine to see if the problem persists. If you have an ac adapter kit check to see if the problem persists when connected via the mains.

Thanks for your replies.

Before I send of my camera I will get in touch with both companies (camera repair, Willpower and H Lehmann, John ).

Seven Wishes latest firmware loaded is 2.0.0. One battery was purchased about 3 months ago and it is a Canon one. I do not own a battery grip or mains adapter so cannot try using AA batteries.

Thank for your fast replies.

It happened with mine. I took it in for repair,he took the back off put it together again and said it was working perfectly .I have never had any bother since. It sounds Crazy but make sure you haven't mistakenly switched the camera off.

Don’t confuse the Date and Time battery with the main power supply battery … this is a separate coin type battery and if drained can throw up some weird functionality … it might be worth spending £2 and changing it to see if that fixes the problem.
An AC power adapter kit for the 7D can be bought for less than £15 and while it will not fix the problem directly it will certainly rule things out … if you can shoot via the adapter, the problem being face could well be the battery, or the contact terminals on the battery or chamber. It will allow you to reset the camera to the factory settings and allow you to update the firmware without fear of the battery turning the camera off. All of these suggestions may well solve the problem for a fraction of the cost of sending the camera away for repair.

I had a similar problem but with a battery grip.
The camera would turn off intermittently when used in portrait mode.
The problem was with the catch on the battery compartment door.
When the door is open, just to the left of the actual catch is a sprung pin which is pushed in when
the door is closed. This could well be a safety feature to allow battery contact only when the catch is fully
closed on the battery door.
In my case the catch had loosened slightly over time so all that was needed was to bend the catch gently to make it
'tight' again.
This was about 3 years ago and I've never had a problem since.

PS.....I've just had a look at the battery compartment on my 400D and there is a similar pin in a recess to the bottom left
of the battery compartment, so if the 7D is the same, I would double check there is nothing stopping this pin being compressed.
And make sure the battery door closes tight.

OK maybe I'm being silly here but........
You were quick enough to ask people here for a solution to your problem.
Some good people replied and tried to offer a solution to help you.
You were active on this site yesterday yet you haven't bothered to update your own topic for two weeks.
You could at least tell the people who tried to help you if your problem was solved.
Is there a reason why that would be ?
Do you not think that your experience may be of help to other 7d owners ?

Well that's good news.I hope it isn't going to be an expensive repair Grin
Let the forum know of the outcome as it's always good to know .........forewarned is forearmed etc etc.
I've only had reason to deal with Lehmanns once and I couldn't fault them at all.....great service at a very reasonable price.............I hope you have the same good experience I did.
