Really thorough, well written manual as expected from David Busch. In 2004 I bought his guide for one of the first Nikon digital SLRs, the Nikon D70s, and it was also excellent and informative, not only about how to use the camera itself, but also with very useful and clearly stated information about how to shoot various kinds of photos in general. After that early manual, I expected this one to be excellent as well, and it is. Everything is clearly written and easy to understand. There are plenty of photos to illustrate pretty much every topic he discusses, and all the photos are extremely helpful. to your comprehension of a subject.The manuals (usually a downloadable PDF now) that come with cameras these days are not nearly as complete or easy to understand as camera guides such as this one. The Nikon manual might tell you what setting choices are, but it doesn't tell you why to choose a particular setting, whereas this guide tells you why you should or perhaps should not choose a setting. This is a great book to read to understand your new D5600, and after studying it, it is still a great reference that you will use down the road. Worth every penny and highly recommended, especially if you are new to digital cameras. The D5600 is a fabulous camera, and it's worth your time to fully understand all that it can do.
