Sigma 150mm Tricky AF

  1. So I've noticed that sometimes on this lens the image is in focus but the shutter won't release. I found it frustrating yesterday when I was trying to shoot some wildlife.

    I guess after the lens focuses in I press the shutter and nothing happens. Is there anyway to override this? For full time manual lenses I thought they would shoot even if it was OOF?

    Is your D300 on C or S mode (the little trigger under the lens release button)? Sounds like it's in S mode...switch it to C, and you should be able to trigger the shutter regardless of focus.
  3. Bingo, when I was flipping it from C to M I must've left it on S, I just blamed the lens :p
