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