I have a D5100 but am finding it tricky to buy a lens for a reasonable price.So I bought the following:
SIGMA MINI-WIDE11 1:2.8 28MM LENS (with an M42 screw mount)
and
M42 screw mount lens to Nikon F mount adapter.
It all connects together but the camera doesn't detect the lens.Is there a way to get my camera to detect the lens?
