This PhotoBert CheatSheet is an abbreviated, easy-to-read, color-coded guide to the controls and settings of the Canon EOS R Digital Mirrorless Camera. Authored by Bert Sirkin, it addresses a comprehensive range of camera functions on an 8.5 x 11" double-sided sheet with a 3-mil thick waterproof lamination. Additionally, the PhotoBert CheatSheet is pre-folded into thirds. When completely folded, it measures 4 x 8.75" for portability.
