As of a short time ago, Photographer’s Guide to the Leica D-Lux 5 has been available for sale in the iBooks Store for Apple iBooks. If you have the iBooks app on your iPad, iPod, or iPhone, you can go to the iBooks Store and purchase the Leica D-Lux 5 book through the iBooks Store directly from your device. I don’t know of a way to provide a direct link to the iBooks Store; you can search for the term “D-Lux 5” to find the book in the store. It is priced at $9.99.
