I'm currently using a D700 and D300s and I'm looking for a camera to shoot video in addittion to something small that the wife will actually use. How good is the video from this camera? Can I change apertures while shooting a video? What video features does this offer compared to my D300s which is limited to 5 minutes and cannot change apertures while recording. Long story short, I want to shoot video with more control that what I currently have and I'm hoping based on cost this is the best way to go. BTW, 24mp would be nice to have too!
