Hi all,
I got a Nikkor lens (50mm F1.4) today. It is bigger/heavier than pentax lens, feels very solid. But its focus/aperture rings are not as smooth as pentax's.
This is my first Nikkor lens. When I mount it ( I am not even sure if I mounted it in right way), I can only rotate it slightly. It seems stay on my pentax fine, but I really don't feel secure about it.
After I took a close look of the mount, I noticed that there's a screw which is above the surface. See the picture below.
I wonder if I need to remove or replace that screw.
Thanks.
