Canon EOS 90D Pocketbook: concise camera field guide Paperback – December 9, 2019

A lot of information on camera.

I have been buying electronic equipment for 30 years or so. This book was the first to explain the ins and outs of the operation of any. It was clear ,concise and to the point . I was using the equipment at a satisfactory level in record time .

This booklet is 54 pages. It is small, concise and can nicely fit in your camera bag. It cost 7.95 in British Pounds which equals 10.75 in dollars. It is severely overpriced on the Amazon site for $17.44.
