Please post your impressions in a day or two after getting the grip. I would really be interested in the following: - how strongly does it ayah to the camera? Is there is any wobble. - how does the grip feel relative to the camera? Thin hollow plastic? Rubber inserts? - how does the shutter release button feel compared to the on-camera one?
Also, on my D90 there was an issue with metering the battery charge in the grip when using AA batteries. It would show full charge which would drop to 2/5 with time and then to fully discharged bypassing the intermediate charge levels.
