Hi guys,

was using my 5D yesterday night for some long exposures. It took few dozen pictures. It was a bit misty near a lake. Not drenching mist but a bit misty and few tiny sparkles(or the misty spray u get near a falls).

I took like 2 pictures in the mist.

I had the Mirror Lock enabled. So i locked the mirror and enabled bulb exposure and enable the shutter.

After enabling the shutter i got a err 99 on the top LCD

The camera focuses well, the camera performs exactly the way the way it should. But the shutter is not working properly.

Rather it appears as if the shutter is stuck on the mirro mode forever.

I removed the batteries, changed the CF cards and reset all the camera settings.

The lens used was 24-105.The lens performs well on the 1D(lucky i had a back up to continue with pictures)

The CF cards all work well on the 1D.

After focus confirmation, when i pres the shutter the mirror stays in the locked position. With the lens on, it stays in the position. When i remove the lens the mirror goes back to its original position.

SO i tried without the lens and for the first shutter press, the mirror appears in the lock posuition and for the next shutter press it gets released. NO PICTURE is taken

When i klook at it in the light i see that the shutter is in the Closed position with the Mirror up, and it tries to open a bit and its stuck. I can see a 3mm sensor while the rest is covered with the shutter

Any body with some helop would be great. Since i am going to a trip to India tomorrow, i wont have enuff time to send it to canon to repair. Alos though there are service centres in India, i am not sure i can use the cameras USA warranty there.

PLEASE HELP GUYS

Can you tried with a new(er) battery?

Sounds like this is a normal operation when the mirror is programmed for lock-up:
1st press ths mirror goes up
2nd press the shutter release and the mirror goes down

The shutter is only energized when its released so it might draw more instantaneous current than your now used battery can supply... You'll need a spare battery anyway, it does not hurt to try with the amount of time you have left before travel!

Did you check the other little cmos battery, a little CR2016 lithium 3v cell in the camera?
Strange things can sometimes happen when it starts to go weak.

Update

Got the camera back from canon. There was some problem with the internal mechanism of the Mirror which prevented the mirror to operate normally.

THey have changed those internal parts and along with that serviced the camera completely changing any parts if neccessary and cleaning.

This is what i recieved from the Canon. They have cleaned the dust in the view finder and the camera works fine now

Have no idea what was the problem, as long as it works

Thanks all

It took exactly a week to send, repair and get my camera back.

They were pretty fast.

They got the camera on Thursday, repairedit bymonday and sent it to me by thursday )

Please feel safe to send the camera to Canon. I guess they have a decent service centre. I sent to the one in Irvine CA
