Hi All,
I have recently purchased a Sigma 28mm F2.8 lens, which appears to be designated a "Super Wide". The lens appears to be working normally on my D80, except for an issue with the aperture - the widest I can open it is F3, not F2.8. This appears to be strange, as my Nikkor 28mm F2.8 jumps straight from 2.8 to 3.2; it doesn't stop at 3.
All other aperture stops appear to work as expected, and the lens takes some nice pictures, with fairly decent auto focussing (though it does sound pretty clanky, which I gather is expected of this particular model).
Can anyone suggest if this is a niggle with the camera-lens combination, or if the viewfinder display of aperture can generally be relied upon? I'm trying to determine if the lens is faulty, or if this is actually not a problem at all.
Thanks for any help!
