Query: The Nikon Field Guide

As an amateur photographer I found the book to be pretty much a complete waste of time. The author has given no creedence to readers who havn't invested heavily in purely Nikon gear such as lenses and flash units. Descriptions of shooting scenarios are too concise and again apply specifically to all Nikon apparatus.I would have found it more useful if the author had concentrated his advice with information specifically on how to get best use out of the functions available on the camera body itself i.e. Aperature & shutter priority modes when shooting in different conditions. I found the glossary of camera's which takes up a good 100/150 pages to the rear of the book a waste as all this information is copied direct from the user manual of the associated camera's as anyone with the camera's reviewed will know.All in all a very dissappointing read and one which I now never refer to.
