Rest assured that all of my e-books are written in an easy-to-understand and non-technical way. The only few complaints I received over the years were from Pro-Photographers and Electronic Engineers. They thought my e-books were too simple. Can't please everyone! You can download a sample of all my e-books here

The e-book for the K-3 will be my biggest e-book thus far, somewhere between 300 and 400 pages. You are absolutely correct when you say that Ricoh/Pentax produced the smallest manual ever, for their best and most complicated DSLR ever.
