Buffer Speed / MB-D12 DX 12bit
Just ordered my 800.
A couple folks another site claim that they get 6fps with "a deep buffer" using the Nikon MB-D12 grip with either AA batteries or the D4 battery with adapter, while in DX crop mode, 12 bit.
Can anybody confirm this?

Yes, the grip with the D4 battery or AA batteries gives you 6FPS in DX crop mode shooting either in 14 bit or 12 bit RAW.
The buffer depth (how many shots you get before the buffer fills)depends on your memory card speed.
Using the Lexar 1000x CF cards I get the below results without a grip....
In 14 bit RAW
In FX I get 20 shots @ 4 FPS
In 1.2 crop mode I get 23 Shots @ 5 FPS
In DX crop mode I get 59 shots @ 5 FPS
In 12 bit RAW
In FX I get 42 shots @ 4 FPS
In 1.2 crop mode I get 85 Shots @ 5 FPS
In DX crop mode I get 100 shots @ 5 FPS
As you see with a fast card - even without the grip the buffer is quite deep in 12 bit Raw across the board. The extra frame per second gained by the grip would probably reduce the number of shots a little bit but the buffer would still be "deep.
I would guess that in DX crop mode 14 bit @ 6 FPS you would still get you over 30 shots and 12 bit would still be over 80 shots before the buffer slows your frame rate.

Thanks Dave - good data.
I'm not sure the 800 will ultimately fit the bill for every assignment, but then again, neither will the D4. I've ordered a fast CF card, and will test the 800 a bit. If need be, I'll rent a D4 as needed.
