Besides Haptikverbesserung this handle has two Nikon EN-EL3e battery packs space. Those who want to can, instead, also R Insert the supplied battery cage 6 batteries.
The biggest advantage is the increased life battery power the camera. Basically, the D 90 legendary 1850 pictures in it, with partial use of the flash after all, still in 1250! For comparison, a Canon EOS 50 D are possible without a flash even proud 1200 photos, with flash only 770th
In LiveView it is even more striking, Nikon creates flash so the 200 shots, Canon bends at not even 140 shots a (read at Chip.de). I could understand these values in everyday life.
By Batterriepack MB-D80 I have with different recording types (flash continuously + some LiveView pictures) made remarkable 1967 Photos (image count in camera) before both accumulators are painted the sails! Advantage of the battery grip accesses each battery separately, one after the other, so that you "can go only with a Nikon EN-EL3e, while the other is charging.
Class thing the - also 2 Battery diagnosis fields are then displayed on the camera monitor, each with maturity and pictures counter!
Another advantage with the handle upright shots succeed better because the camera can be kept affordable. Unfortunately, the additional trigger has no, repeat no intermediate pressure point to focus regulation! In practice, this circumstance interferes but little because the autofocus is good even without adjustable pressure point. I was there less disturbed than other users. Against accidental firing, the release button can be locked.
Adjusting wheels and buttons are available as on the camera, including the handle, so that you also in the "upright" mode can take full advantage of the most essential camera settings. The Individual Key Stellradbelegung the D 90 is also transmitted to the handle, so it should be.
The disadvantage, of but high price. But on my Nikon I verbaue Only Nikon Accessories!
Conclusion:
The MB-D80 you need on holiday and at excursion rarely or not at all accumulators are recharged, or as replacement batteries to carry around - Super! Who had missed once in expensive overseas holidays good snapshots due to low batteries, and far and wide no outlet were still raise disposable batteries, know this energy insurance greatly appreciated. Hochkanaufnahmen gelinger better because the implement can be kept relaxed. Additional buttons and adjusting wheels facilitate handling of the entire camera. A big plus, for the Haptikgewinn the total Packetes D90 + MB-D80.
Because of the high price and the non-existent pressure point when trigger only 4 out of 5 stars. Absolute buy recommendation.
