Hey Everyone,
I just picked up a Nikon 300mm F/4 Af-s, but there seems to be a problem.
I attached it onto the Nikon D300.
And when it tried to focus, the was a high pitched whinning noise.
It kinda sounded like someone scratching their nails on a chalk board.
What do you guys think is the lens faulty?
And it sometimes doesn't even attain focus.
Thanks!
