<<His comments about folks not being attentive to the notice that he emails were uncalled for.>>
I guess we all have a bad day, even on here I've seen uncalled for comments from Nikonian posters in some threads. In my experience and the D800 book is the first I bought, I have written to him 3 times to clarify a point and he has replied promptly and politely.
The Nikonian resource is of course very valuable and always my first point of call, but very occasionally it can be a bit hit and miss and inaccurate statements are sometimes made when those responding don't know the answer fully themselves. I have been found guilty of that myself in earlier days
Give the guy a chance, despite what some think his references are absolutely superb as are Darrell's.
