Jeff Revell (from PhotoWalkPro) has been a professional photographer for 25 years.

His book "Canon 50D: From Snapshots to Great Shots", published earlier this year, is written specifically to teach Canon 50D owners how to take great photographs, and to learn how to use the camera's features in different situations.



This book is clearly targeted at people who own a Canon 50D. It focuses specifically on the features, functionality and controls of the 50D, and as a result, would not be of much use to anyone who doesn't own a 50D.
