This book is the larger-sized paperback version of Photographer's Guide to the Sony DSC-RX100 III. This version of the book contains the same content as the earlier version, which was published in September 2014 with dimensions of 5.5 by 8.5 inches (140 by 216 mm). The new version of the book, which replaces the original version, is being published at a size of 8.5 by 11 inches (216 by 280 mm) in order to present more information on each page, which keeps related images closer to the text they illustrate and reduces the page count, making the book easier to manage.

This book is a complete guide to using the Sony DSC-RX100 III camera, one of the most advanced, but still pocketable, cameras available. With this book, author Alexander White provides users of the RX100 III with a manual covering all aspects of the camera. Using a tutorial-like approach, the book shows beginning and intermediate photographers how to accomplish things with the RX100 III, and explains when and why to use the camera's features.

The book includes more than 400 color photographs that illustrate the camera's controls, display screens, and menus. The images also provide examples of photographs taken using the RX100 III's Scene mode, with settings optimized for subjects such as landscapes, sunsets, portraits, and action shots; the Creative Style and Picture Effect menu options, with settings for altering the appearance of images; and features for continuous shooting and shooting in dim light.

The book also provides introductions to more advanced topics such as infrared photography, astrophotography, and digiscoping.
