I DO NOT want the 7d's crap AF system. Instead of shooting with my 7d, its been a glorified paperweight for 6 months. Been back to canon 3 times. Refuses to consistently focus. That system sucks.
the 7d has a great form, and is a joy to use, but those high noise images and af trials have me ready to trade it in.
Sounds like you had a lemon. I would be thrilled with a lower cost FF with the 7D's AF (assuming the other specs meet my needs of course). Being a current 7D owner, it sure would make it smooth going back and forth between bodies.
