If you are good with processing RAW images, you can get better noise reduction with DxO Photolab or PureRAW than the camera will give you (1-2 stops less visible noise, in my experience).
thanks neuro! will be testing these setting on some chimney swifts, they are speedy little guys so they are perfect for tests, and i'm decent with raw edits, at least better than a couple of years ago, i'll look into dxo photolab and pureraw as 1-2 stops lest noise sounds incredible!
