My beloved 7d has been giving me grief with an Error 30 message lately and I'm not sure how to proceed. I bought the camera from a user on here in June of 2012 and it has been great since then. There are only around 35,000 clicks on the camera. I have a backup 50d to use, but I've been extremely spoiled by the autofocus system on the 7d (compared to the 50d) so I'm having withdrawals.
In December I purchased a Canon battery grip because I've been shooting a lot of sports for my college newspaper. I shot a bowl game over the winter break with the grip installed and had no issues. The first basketball game after our winter break is when I initially had the problem. It was towards the end of the game, so I didn't think too much of it. Then the following week it happened again while out on a news assignment. This past Wednesday I shot another basketball game, soI brought a camera from the school just in case my 7d went down again. Sure enough, it crashed before the game even started. My 50d + the school's 60d is not my preferred combination for shooting sports, so I really want my camera back in action.
I've tried disabling live view, taking off the battery grip, and doing the slap trick, but nothing seems to be helping. I haven't been able to get the camera to do an Error 30 at home, only at a sporting event or while on assignment. I've read about other people having this happen with battery grips, but I don't know if that is the cause of my problems.
Are there any known solutions besides sending it in to Canon? Could my grip be the cause of my problems? I'd be pretty bummed if this expensive piece of kit is the cause of me spending even more money.
Most of what I am seeing points to me spending around $250 for a shutter replacement. For anyone who has been in the same boat as I am, does this seem accurate? Is it worth it for a camera that you can buy used for about $500? I'll probably just keep the camera forever if I do send it in. I'm just pretty upset that a shutter rated for 150,000 has died so quickly.
Sorry if I rambled, I'm not too thrilled at the moment. I've also realized my username on this site is very reflective of the 15 year old version of me that made the account in 2009.
