Sorry if this is a dumb question but I have browsed the groups and cannot find the answer to this.
I have a D7100 and I bought a Nikon AI-s 105mm f/4 lens and PN-11 to experiment with macro photography.
When the lens is off the camera and I turn the aperture ring, the aperture opening does not change but when
I put the lens on the camera and turn the aperture ring, the camera display changes to match the lens
aperture setting.
My question: is there a sure way to find out if the lens is working as it should? I thought that the aperture
should be seen to physically change if I turn the aperture ring while it is off camera.
Thanks in advance
