I know this has been aired before or I wouldn't know it existed, nor that it doesn't on my D80, I think it came in with D300.
The question is how much of the camera shake originates from the mirror action? I am assuming a less-than-ideal tripod (as I can't afford or physically carry) a robust one. Secondly I am an 'outsider using' a 80-400VR for landscape and hate most w/a shots. The 80-400VR has a mount that balances camera+lens extremely evenly.
Using such tripods as I have, an old cheapo or Optera 460 pro, I find i actually get worse, ie obvious movement double-imaging, than handholding.
Do people generally use MUP on tripods, or is a little known cult?
If so, can one in fact get away with a lighter tripod than otherwise using a longish lens?
(I know I need a camera with MUP - am working my way towards pulling enough out of life savings for D7000!)
