If you have a D300, I personally wouldn't upgrade to the D300s just for the sake of video capability - if video is that important, then get a camcorder! I would have thought an upgrade from D300 would be to a D700.

Agree, it's not worth it in its current state.If you have a D300, I personally wouldn't upgrade to the D300s just for the sake of video capability
Not really, the only "upgrade" would be a full frame sensor. Hardly worth the cost of selling a D300 and buying a D700 for twice the price for a fullframe sidegrade.I would have thought an upgrade from D300 would be to a D700.
