Hi you answered a question I had of which book is best for learning to use the nikon d7200. Did you decide which of the two books you think is best. You don't need to send me one as stated! I would just value your opinion. (Or should I just get both of them?) This is regarding a post from back in January. Thanks so much, Robyn Rocke

What is the best book for help learning the Nikon d7200? A few I know of are Nikon d7200 For Dummies, Mastering the d7200 by Darrel Young, Nikon d7200 Guide to digital SLR photogaghy by David Bush, Nikon d7200: From snapshots to great shots.

I have a Nikon D7200 and would like to hear some dialogue on the possibility of using back button focus for the purpose of achieving continuous focus while videoing.
