Re: Exposurecontrol on Nikon D90

While the d90 doesn't let you manually control exposure, you can lock the exposure before shooting. It tends to overexpose in the LiveView mode, so aim the camera at a brighter part of the scene before engaging the lock. You also can manually set your F-stop (and hence your DOF) before engaging the LiveView mode. The camera seems to default to a filmic shutter (1/48th or so) unless you are in bright light--here you need ND filters, just as you would on any other camera to maintain the shutter speed.

The d90 is a great entree into video DSLR shooting--a lot of very nice projects have been shot on it (check out the vimeo Nikon d90 group for examples). Hopefully Nikon will give us a firmware update with manual controls and come up with a newer body in the next year or so with improved capabilities.

Personally I think that the GH-1 is over-rated, and that the future will be with Nikon or Canon's line of cameras.
