Spent a half hour with a D7000 and here’s my brief conclusions
Likes:
Solid Construction, well laid out menus
Shutter and ISO control while shooting
Dual SD slots
Dislikes:
No aperture changing while in Live View. If using a electronic lens, you must stop recording, exit liveview and change aperture.
Conclusion
Without going into the video quality (which matches Canon at 1080p – moire and all) the inability to change aperture while in liveview is a deal killer unless you plan to only use manual lenses. What was Nikon thinking?
