I just learned that Sony has released a firmware upgrade to Version 1.20 for both the RX100 IV and RX10 II camera models, which are quite similar in their menu options and operation. The upgrade provides the same change for both cameras. According to Sony, the purpose of the new firmware version is to “improve a focus shift condition with HFR (High Frame Rate) recording.” That problem evidently is the one discussed in this thread at the dpreview.com forums.
That is all the upgrade is designed to do, so, if you don’t use HFR recording (super-slow-motion video recording), you may not need the new firmware. However, I always install new firmware versions as they become available, and it probably is a good idea to install this one as well.
As of today, the paperback version of Photographer’s Guide to the Sony DSC-RX100 IV is available for ordering through Amazon.com. The paperback book, which sells for $26.95, contains the same text and images as the ebook versions, which have been on sale for about the past week. The paperback book is 8.5 inches (216mm) by 11 inches (280mm) in size and has 248 pages. Like the e-versions, it includes a complete Table of Contents and Index.

As of today, Photographer’s Guide to the Sony DSC-RX100 IV is available in downloadable versions for the Kindle and iPad, as well as in a PDF version that can be read on any computer or other device that has software for reading PDF files. The new book is 314 pages long in its print and PDF versions, and contains more than 450 color illustrations. The print version of this book has a larger format than the earlier guide books in this series—8.5 by 8.5 inches (216 by 216mm), instead of the 8.5 by 5.5 inches (216 by 140mm) format of the previous books. With this format, the printed version uses a two-column layout, which includes more information and images on each page than in the earlier books.
This book, which provides guidance for the use of all features, menu options, and controls of the Sony RX100 IV camera, is available now through this site. In the near future, it will be available from Amazon.com and other Amazon sites, first for the Kindle and later in the paperback version as well. The paperback book will sell for $26.95; the ebook editions will each sell for $9.99 through the Amazon, Apple, and other sites.
