Nikon 300m f2.8 AF-I "buttons"

Discussion in 'Lens Lust' started by bvonarx, Jul 3, 2008.

  1. Ok so I just bought a the above lens from a Cafe member (thanks Jbear) and have the following dumb question. What are or is the purpose of the four round "buttons" on the end of the lens? They do not seem to have an obvious purpose. Any ideas?

    My guess is that they're an AF lock

    Yes, they are focus lock buttons.
  4. Nice one, I'll go give it a work out.
