Hi all,

My birthday and inumerable Christmases arrived all at once and I am now the happy owner of a Canon 7D. I have spent many hours playing with the basic settings. At this point I am happy my understanding of the basics settings for the camera, however, I find the supplied manual to be inadequate when it comes to the miriad of options available.

The manual certainly describes how to change various settings but it is rather defective in that it does not adequately describe (for me at least) the affects of particular settings on the operation of the camera or the end image.

I am looking for a good user guide that will fill in the deficient details. I realize that I could experiment, but looking at the variety of options and permutations available, I suspect that I will be old and grey before I have covered them all. David Busch's name has been mentioned on other photography forums. Can anyone suggest a guide which could be useful for me.

I appreciate any help offered.
