This book is full of information on the D300s enriched with many actionable practical tips. Very commendable is the fact that the author at almost any function or setting the benefits and consequences shows and its recommendation or their own personal attitude reveals. With this basic setup the reader has ever seen a common thread and can then - where desired or necessary - deliberately deviate with the knowledge of what has for effect.
If you want to look for something Negastives, then I would say that the book is partially a bit longwinded. Although the author writes loose very understandable and almost friendly, but just latter can sometimes seem a little talkative. Some information he could well provide compressed for my taste, but perhaps this makes it not quite as technophiles only possible to understand the complexities of such a camera and can take up a lot of information.
CONCLUSIONS: Compared to many German books the reader here many times more information and for half the price! The book is thoroughly recommended a comprehensive treatise on the D300s and the good price / performance ratio.
