When is a D300S Better than a D700?

<p>There are some perks to using DX sensor as have been pointed out here. I upgraded to FX about a year ago, but still have DX lenses I'm unwilling to part with (e.g. 10.5mm, which is an AMAZING fish eye). Also, in relatively good light conditions I like to take DX for a ride with my other lenses such (e.g. 80-200 2.8) and take advantage of the crop. The camera is also lighter, so sometimes it's more convenient. I also tend to use it for projects such as time-lapses, etc where camera is more likely to be exposed to more abuse and result in less expensive repairs (knock on wood..)</p>
