Jesse Lind Oh, ok, thanks so much for helping me out with this! :)
noun Great!
Jesse Lind Thanks a lot, I think this might be the problem because I shoot on 30 seconds a lot and it does seem like they are moving a little bit.
Antoine Beauvillain Yes, you might have to set a higher ISO and shutter speed to get a clearer shot. It can be a bit more work afterwards, to compensate the noise (depends on your camera body and sensor).
Maciek Korsan go to the live view and set focus manually - it'll probably be just before the infinity sign on you lens. also stars are 'moving' so use the rule of '500' - davidkingham.com/blog/2012/11/...
Marcin Chęciński Which lenses? If there's a marker of infinity then it should be in focus if you play around with it (it could be not actually at that marker).
