Another thread asks about David Busch's D300 guide. I was considering this one as well as others, including Thom Hogan's. Mr. Hogan's primary guide is on a CD but he does offer a "shooting manual" and information on Capture NX2. I can't tell how well written each is for beginners to this camera (or to Capture NX, for that matter). I would appreciate hearing your recommendations for guides, manuals. Thank you.
