today i ' ve tested my new Nikon D300s. I 've noticed that the picture in the viewfindet move down und up for a very short moment after release. I use my nikon 16-85mm VR with VR = on. This problem doesn't appear every shot. Then i switched to my Nikon 70-300mm VR (with VR=on) I can see the same trouble. On both lenses appear this problem only with VR=ON.
But when i use the same lenses with my old D300 I can't see this.
Then I test the lenses with the internal flash. Then every shot the pictures in my viewfinder is shacking down and up!!!! Could this be a voltage problem? VR=on + Flash -> not enough electricity ???
Do you have the same problem? Please check your Cam
(Sorry for my bad english, but this problem reduce my joy for my new D300s)
The pictures with this problem are not sharp. They looks like 2 shots (double-shot).
