My well-reviewed Sony a6000 guidebook, out of print for the last six months, has been adopted by Rocky Nook. It should be available in both printed and Kindle, Nook, and PDF formats by late-May/early June. Thanks for your patience! Don’t pay the $100-$700 this book is going for on eBay and elsewhere. It’s a good book, but not worth it! Thanks for your patience after my original publisher closed its photo book division.
