Review of David D. Busch's D500 Guide1/1/17 I bought my D500 and MB-D17 ext battery pack at the end of November 2016. I had been a D300 user for 9 years. I have my “stable” of Nikkor lenses already. I am not a professional photographer. I like nature material, but regard myself primarily as an “historian” both for our church and family, and for friends (such as memorial services and celebrations). At a minimum I needed to maximum my low-light capability for those. I have been very pleased with the D500 in that regard, usually shooting around 20-32K ISO. Until I got David’s book, I was a quite frustrated with Auto ISO and live view focusing. The NIKON Manual was not much help in either area. Buried in it is the info to select options for most everything, but virtually no help as to WHY or HOW to use a feature.I got David’s book 12/24/16. His description of his book is very accurate. “Rather than write a book for just one of those two audiences” (newbie or veteran), “I’ve tried to meet the needs of both.” In over 500 pages I believe that he has succeeded in both.I have tabbed my book, and even though I am only 2/3 of the way through it, I have tabbed over 2 dozen MAJOR techniques or features in the D500 that are new to me and which want to incorporate into my shooting.He has a way of explaining what the features are and how to make features work (or why he doesn't recommend using them) that I have found to be very friendly (in a couple places humorous). There is so much meat in the book that I have expended well over 20 hours so far carefully reading and marking it. Features that the Nikon Manual just mentions are expanded upon so that they can be considered and implemented. Just reading the Nikon manual, for instance, about High Speed Sync (for flash) left me cold, and I never would have tried it. After reading David’s explanation of what and how, it will be a “meat -and-potatoes” feature of the D500 for me.I like the organization of the book, and its index beats the NIKON manual's index hands down. Despite his book having so much info, David does mention that the reader should refer to the NIKON manual, too, and sometimes I will cross reference to the manual when David brings up a feature that I had no idea existed. He also provides some equipment recommendations based on his own experiences. If you don’t have your “stable” of lenses, you might hold off until you read his section on lenses.Things about which I knew enough to get by from the D300, he explains in such detail that I can use them much more to my advantage such as how to get a 30 second self-timer, getting the correct exposure with the spot meter, the best use of my SB-800 flash, and much, much more. I appreciate the level to which he provides the technical aspects of a feature, piece of equipment or a method.His book is printed on very high quality and tough paper so that all my underlining with Sharpies and highlighting has not bleed through, nor have I had any instance of the paper tending to tear when I move tabs or post-it-notes. This is important to me since I will refer to his book as my D500 bible for a long time.One last aspect that is more than just icing on the cake, is that David gives you a way to communicate with him. He has responded EVERY time I have emailed him and usually within a matter of an hour or two. I received one email response from him to an emailed question in less that 6 MINUTES.If I could, I’d give his Guide (and him) many more stars than the normal high of 5.Bruce
