I've been looking to upgrade my camera for awhile and was planning on upgrading to a d300s until I read the dpreview review of the d7000 that just came out. It seems like the d7000 may be a good option, though the d300s is a more professional camera. I love my d200 and have used it for years but need a camera that operates better in low light situations. I shoot a lot of portraits and concert photography and am looking for something fast, dependable and sturdy.I don't work much with video now but it will be nice to have it in the camera. Any advice?
