> I really like the increased battery capability and use EN-EL4a batteries in my D300 and D700 grips as well as the batteries in the cameras. I consider a camera without a vertical shutter release to be crippled. To each his own. <
I concur with all the points made here. First time I used two batteries in the grip for the D200, I waited for a camera prompt to switch batteries - happened seamlessly. The D3-type battery that's available for the D700 grip will provide even greater capacity. I have large hands so the camera/grip combination balances and handles well for me and enables single-handed use.
> Aren't we lucky to have so many choices? <
Remember 30 years ago when Nikon life was a choice between a Nikon F2, F2S, or a used F, or a Nikormat EL or FT2? Body choice was relatively easy; lens choice, however, was the hard one. And when the EL was introduced, so much photographers proclaimed, "There goes the neighborhood." Now the F2S plus MD2/battery compartment was heavy - late 50's Cadalac heavy!
