Arkadaşlar Canon 7 D kullanıyorum ve dikey kadrajda birkaç fotoğraf çektikten sonra ''error 30 shooting is not possible due to an error turn the camera off and on again or re - install the battery'' uyarısı alıyorum, bunun sebebini bilen var mı? ne yapmam gerekiyor ayrıca? makinayı yeni alddım sahibi 8.000 shutter da olduğunu söylemişti, dış görünümü temiz ama daha önce 40d kullanmıştım hiç böyle bir sorun ile karşılaşmamıştım
Pek hayırlı haberler yok abi

"Error 30 is a problem with the shutter. Often the shutter is either stuck open or stuck closed. On Canon DSLR's its often stuck open often from using LiveView.
If its under warranty send it in. if out of warranty, or you lost your sales receipt, then you are looking at $180 plus 40 bucks shipping and anywhere from 3-6 weeks to get it back(closer to the 6 week time)---to replace or repair the shutter mechanism.
Can you do something yourself? Yeah. Turn off live view permanently. Live view opens the shutter completely, a bit of an un-natural situation for a DSLR with a focal plane shutter. Read up on focal plane shutters on wiki. They are never all the way open. I doubt whether they were completely redeigned to operate in the full open position.

Then you have two choices.
I accept no responsiblity for either of these extreme solutions, and its your neck if you decide to do these stupid things without a net.
The first might damage you camera... of course its already a paper weight, but don't blame me if you REALLY REALLY damage it, as I'm warning you.
You give it a couple of whacks with your palm to dislodge the stuck shutter. This worked for me. It made this weird noise, and I turned it off, and then back on again and it works again. Then set it for multiple frame and kick off about 60 or so frames to lubricate the shutter mechanism.
Another choice is to set it for a long exposure,and interrupt the electrical circuit by either opening the battery compartment or pulling the battery. God only knows what this might do besides what you want. But its supposed to give it an electrical jolt from the sudden loss of power to dislodge the open or closed shutter. Its been known to take as many as 15 times the get this to work. Also set it on multple frames then and kick off about 50 framdes to lubricate the shutter.
Good luck. But I accept no responsibility if your camera becomes a permanent paperweight by trying any of these foolhardy techniques.
