Vertical shots using the existing controls on the handle (AF-On button, shutter button, 2 dials) are a pleasure. The quality of the handle is actually quite excellent and is not in accordance with the high quality of the D300 / D700.
I operate the MB-D10 with an additional EN-EL3e battery, alternatively you can also 8AA batteries (recommended: Eneloop) in the recording supplied as an accessory use and then an encore even higher burst speed (7.5-8 fps ). But then the handle is also more difficult, which is why I use the AA battery only as a backup. What I like very well, the possibility of battery grip battery to remove (to load it) and the MB-D10 is weiterzubetreiben on the camera battery.
Please note:
Choosing the right battery order (menu d11) and correct assignment of the AF-ON button on MB-D10 (menu A10).
Conclusion:
For the current price of the MB-D10 is highly recommended and you get a tural value. I am glad that I bought it did.
