I feel like I am in a similar boat with my 7D. It misses focus on subjects that should be incredibly simple to hit. Mine is super grainy at all ISOs and has pretty significant noise banding at anything above 200ISO. I'm taking it to Canon this week in hopes they can work some magic and fix it.

PS - Yes I read the manual, cover to cover, I'm pretty well brushed up on the AF system, and I came from a 1DmkIII, so I understand how AF tracking works pretty well :) I would also typically expect One-Shot AF to work almost all the time, not to have it almost never work.

OP - I can understand your frustration, but help us help you. We're not trying to cast stones, obviously some of us (myself included) have some unexplainable issues with the 7D and there are many great users here that can help us out.

Nah I think the camera is capable of being awesome. Some people are just more vocal about issues they have with their equipment.

I'm far from giving up on the camera, I think I may just have an early body (it was purchased Sept 09 I think) that had some of the issues that have now been resolved. I'm going to try to get Canon to fix or replace it.

.....

WHAT DO I HAVE TO DO TO GET A NEW BODY FROM CANON?.....

O-kay, deep breath.
this is the only thing we can help with I think.(doing this same side by side was exactly how I finally proved to MYSELF that my 1st 1D mkIII was a lemon, and not just suffering from the same issues that plagued all 1D mkIIIs in the beginning. Until that point I always had enough doubt to be unsure of what the cause fo the issue was.)

If you are shooting another 7D next to this one as you describe, and get good results from the other 7D, then this looks cut and dry.

So all we can do is offer an answer to this one question.
First, contact the vendor you bought it from, ask for an exchange. If it's as new as you say, they should do this for you.

If that;s not possible, then you need to try and get Canon to do it for you.
This is not easy, but it can be done.
Call customer service, be nice, be understanding, do NOT let them transfer you to tech, if they wan tto, ask to speak with a customer service manager,.
Once you get that manager, explain this is a customer service issue, not a technical issue. You have a lemon and want to have it replaced. Instruct them to look up your and the cameras history with service to date.
Without being a prig, let customer service know you have no faith in tech services to solve this issue at this point. Stay calm, but be firm about this. If you do it without flying off the handle, then you could get Customer Service on your side. I don;t know if they can override Tech repair on their own .. but they can go higher up the food chain and get the replacement O-kayed.

If you end up having to, absolutely include all the copies of out of focus images when you send it in... but be firm in that you are sending it in for them to evaluate for a replacement, not a repair.

All of these hoops and jumps are in place at Canon to prevent customer service from replacing perfectly working cameras, they force the system that is to assure that the camera is functioning via tech/repair, but sometimes they misdiagnose.. we are all human. So it takes effort on your part to ask Canon to drop it's S.O.P. for you.

Good luck.
Let us know how it turns out.

I really feel the OP's pain. My 7d, while not as bad as his was only getting around a 40% keeper rate in sunny ideal conditions. This was the same in one shot and servo. After reading endless threads about how it was user error (Ive used 300/350/400/40d before) I stuck with it for 6 months, tried various settings etc. When it nailed focus it was great, but I found I was getting more keepers on a 400d!

Anyway long story short, a shop offered me a good trade in on a excellent condition used 1d3 so I jumped at the chance. Funny enough ive no regrets, and how about that I can use a camera :lol:

Im sure there are good copies around of the 7d but there is no doubt in my mind there are a few lemons floating about also. For what its worth mine was one of the early batch (october 09)

This is what I was doing. Same settings, same lens (24-70L) on my 7D and my buddy's 7D and his files were sharp, well-focused, and nowhere as noisy as mine, which most were out of focus.. Taken seconds apart.

I'm going to explain that to canon when I take it in.

What ISO are you considering noisy? I have noticed in low light 3200 is unusable. But 3200 is good light seems alright. Guess different situations and different opinions.

It's all relative but it just depends on how well you expose the image (and sometimes, not necessarily let the camera determine the shutter/aperture for you).

Here's an image of mine in low light: 1/15s, iso3200, f/1.4, bumped another +1/2 stop in post.

Definitely have the camera serviced if it's not meeting your expectations. I've had no trouble with mine, even tracking moving subjects. The focus has been very good. Maybe they just need to re-align something or calibrate the AF sensors. It's certainly worth trying. It's a nice camera.

Update. My post was directed at anyone who might be reading the thread and wondering if they might have a problem too.

To the OP, take CyberDyneSystems' advice and try nicely to have it replaced. You may indeed have a lemon unit.
