I purchased my 7D a few months back, primarily for a trip.
Having lived with it for a few months now, I must say I'm not blown away with it (I came from a 40D).
The rear screen is brilliant, so clear and works superbly in 'live view'. However, I never use full burst mode (I stick to the intermediate), I never use anything other than centre spot AF, and very rearly use AI servo, I've only ever used the flash twice!!
Am I missing something but it seems (apart from the screen), there isn't anything about the 5DII that I'd miss?
Is now a good time to buy a 5D, OR is it worth waiting a few months for the long awaited replacement (which still might not come), and then pick up a mint used copy.
With the 7D only halfway through its life, prices aren't going to drop much so whether I sell now or in 6 months isn't going to make much of a difference, is it?
