7D Focus parameters explained
 

This is for still shooting only. The focus options on the 7D are great but it sure would be
nice for an article to explain them a little better.. so here it is... I'd suggest you get your
camera out and try out the different options as you read along... its a good read even if
you decide to set the camera up in only one configuration at least we'll know what is available to us.
I for one didn't know that the camera comes with the AF Point Expansion mode and Spot AF mode disabled right out of the box... the Spot AF mode is pretty cool to play with...

enjoy

As always, thanks a bunch for posting this, Ray -- please keep it up!

I need to bundle all of these into a Tips thread.

Good idea on the tips thread.
