What I love most about John Greengo’s books is the curated material that serves up exactly what you need to understand about the features of your camera, put in the context of the techniques required to get an excellent photograph. Explanations are precise and technical enough to provide the relevant context for a true understanding of the principles behind the features..... Highly recommend this book and John’s similar work on Exposure.
