Just because you got a bad copy doesnt mean all of them are crap...calm down and just submit a claim to the retailer.
If it doesnt work then exchange it for a new one. Its not rocket science here.
I said the quality of MY
6D is CRAP. Not all 6D's. I still feel it's a high quality camera despite the on button being very intermittent. I would recommend it to all my amateur photographer buddies who don't shoot sports.
On a side note,
I discovered over the weekend that if I just LEAVE the switch on and let it power itself off or sleep after 1-2 minutes, it works. It's just when I use it and turn it on and off, it sometimes doesn't turn on. Only heavy usage causes this issue. Perhaps the electronics are overheating? If I turn it on and take 5-10 shots, it will work flawlessly when I turn it on and off. But if I take 30-50 shots in 5 minutes or take over 2 minutes of video, it may not turn back on until I wait a few hours and take out the batteries/card and flick the power button on about 10 times to get it to work again.
I haven't dropped it off to Canon yet since I want to use it this week to take some pictures. I just leave the switch on the entire time just to be safe...
It's complicated as to why I can't return it to the retailer. It was part of a 6D kit that my friend and I purchased together. I paid 1600 for the body, he paid 750 ish for the lens.
But he ended up selling the lens to some stranger on Craigslist so now I can't return the full kit in exchange for a new kit unless we HUNT down that guy that bought the lens and convince him to return it.
