This book is a guide to using the Sony a7 and a7R, the first full frame, autofocus system cameras. The less-expensive a7 has a 24-megapixel sensor for shooting rapidly changing scenes; the a7R has a 36-megapixel sensor for ultimate image sharpness. Both use advanced image-processing algorithms and can use any manufacturer's lens when matched with an adapter. The electronic viewfinder gives an accurate preview of the image, ensuring technically excellent photographs by preventing mistakes in color temperature, depth of field, and exposure. All features of the a7 and a7R are covered, including multi-shot noise reduction that allows the use of extremely high ISOs. This book guides the photographer in using the camera's automated features and manual controls to take photographs that are a unique reflection of his or her creative personality.
