Good advice. I turned it off on mine and images imported looking much better for some reason.
Mind you, I do feel that the D7000 has that regular Nikon trait of underexposing as normal - I generally go by gut feeling but it is annoying that such a crisp screen can be off at times.
On another note, finally got a MB-D11 grip yesterday.... ordered off Amazon on the weekend and arrived first thing Monday - £144 plus a fiver postage... good value I thought (relative to the RRP).
Build quality is good and it feels a solid enough unit. Controls are good and the 4-way controller pad does what's asked of it, although it's not a patch on the D-pad on the actual camera body. The fit is snug,a though the screw wheel isn't easily tightened if you have sausage fingers like me. Also, there is still the tiniest bit of play between grip and body, but nothing I didn't have on the D200 grip.
It's nice to have a vertical shutter (and the extra battery space is useful for shooting video) but that annoying trait of the strap falling over the viewfinder every time you tilt the camera is still as annoying as ever after the brief spell I've had without a gripped body
The handling though is definitely improved for me with large hands. I found using the 70-200mm wasn't easy in portrait orientation without the grip - I had an unfortunate amount of shots I'd have to bin due to shutter slap and camera shake - but thankfully, with the grip attached it's much easier to shoot.
I haven't seen or used any of the 3rd-party grips so can't comment on comparison, but I feel £150 is decent value for the real thing that won't affect any warranty if things do happen to go teets up
