I'll bet I know what the unofficial answer was in most cases - PEBV.

I am sure you have one of the few factory defects. I have not heard of many with this problem, if at all.

Both my girlfriend and I bought 7D's recently. It appears that her images are better than mine. We are still testing this. I believe there is a focus problem, and some sorta chomatic problem. The colors don't 'pop' like her pictures do. I'm thinking the AWB might be defective. Again, I'm still testing this...

Maybe she's a better photographer than you? ;) (though it might be true)

Wouldn't the easiest way to test whether the camera is defective is by swapping cameras for a day and shoot and re-evaluate? If your photos suddenly improve, and the quality of hers tanks, then it's likely the camera. But if her shots from your 7D comes out better/sharper, more "pop", well then at least you can ask her to show you what she's doing differently. ;)

I wouldn't doubt she's better than me.. :)

As for swapping, yeah, that's what we were thinking. Maybe even put them in a bag and mix them up, lol. See if we see a difference.
Anyway, I'll throw them on a tripod and use identical settings also. Just gotta find some time...
I'm going to hold off on firmware update till we really compare them..

yes, they corrected focusing errors on mine. However, the work order only said, (something to the effect of ...) "adjusted electrical contacts and bla, bla, bla ...."

They also put the camera back to factory specs meaning I had to go back through menus and reset the camera to my liking.

Before Canon service: Camera would snap lenses to focus instantly. The problem was whether the camera and lens would focus accurately on where the focus point was aimed. Usually not.

After Canon service: Sat on deck, baited railings with peanuts and bird food. Shot 25 images of the backyard regulars. 24 shots returned tack sharp focus, the one OOF shot was on me.

Yes, SOME of the 7Ds exhibit focus error issues not related to user-error. If yours does, send it Canon, they will do whatever it is they do the camera and hopefully return a 7D that focuses accurately.

Everyone who buys a 7D has a bad copy. I will buy yours from you since it sucks.

That's good to know. How long did it take to get it back?

Really quick turnaround on the service. They had it one full day (day after arriving there) and shipped it back the next.

Total time was shipped from OH on Wed., fixed by Canon on Monday, returned to me on Wed., so one full calendar week shipping, repair and received back at my home.

Excellent service, I'd say. Plus, they corrected the issues on my 7D to boot!

I returned mine as it refused to focus in AI servo with any of my lenses. Worked fine in One Shot mode but autofocus was totally inconsistent in AI servo mode. After a couple of unsuccessful football matches, with about 3 shots in focus out of 500 taken, it was sent back to Canon via the original seller and they replaced it with a new one. New one arrived 3 weeks later and works like a dream.

I had mine sent in to cannon a few weeks ago for rear focusing issues. They admitted to the problem and claimed that they fixed it. It is now back at Canon as we speak, but this time it is because the Electronicl Level Display freezes up on me.(They should have fixed this the first time because I told them I was having this issue as well).

My first 7D, sent in, report = Electronic Focus Adjustment, fine after (+: Second 7D, great from the get go. Turn around-hand delivered- 4 days!!!! I lucked out. Canada btw Good luck, don't bust your nut, if you have checked your lenses ( MA ) and are comfortable it's not your your skill/familiarity with it, send it in.

Took me a couple of months to finally say, enough is enough, and it WAS the camera. Had 30,40, 2x50s and a Mark III prior to the 7D, so there are duds out there, but from everything I've read, before and since, it's a fixable issue in 99% of the cases.

A shameful thread, again. OP, please read the volumnous post by those who 'swear' and also swear that the problems they are having are with the camera. You question should more appropriately be: How many users need to be sent back to the factory to learn how to use the 7D?

Stay tuned.
