I have D7100 bought a few days ago the Nikon at local retailers. Since he had the MB-D15 does not stock, I decided to order this still rapidly via Premium shipping to the next day start right away properly. Moving from D5100 to D7100 is ever a step in the right direction have been, but I missed in the D5100 a few essentials, including the ability to install a battery grip. While there are third-party products (which are also so far really praised), but I wanted an original handle from Nikon, even if it is a little more expensive. The quality and the absolute right fit me there are simply too important.
And yes, the handle is simply great! Working with the D7100 and the multifunction battery grip is super comfortable. The camera feels great in the hand, a possible imbalance in benutztem flash becomes beautifully balanced.
As only disadvantage one can quote the rather high price here. But I thus prefer from no stars, because my quality and fit are so important that I can get over it, to have spent more for this handle as a replica, which is perhaps also good but not as good.
