The E-M10 MkIV is Olympus's smallest EVF equipped Micro Four Thirds camera body Don't let its small size fool you though, for packed in that little frame is most of the technology present in its larger stablemates. Like any digital camera, at its heart is a complex menu system with more than 130 entries, many with their own sub-menus.This book goes through each and every every menu choice and explains what it does and why you might want to do it. What my books aims to do is to familiarise your with your E-M10 MkIV and learn to tailor it to your own taste and needs. Having done that, you I think you will find using the camera not only a pleasure but inspiring as well.
