Sigma's newer caps for Sigma/PKA covers the entire mount. This is one thing Sigma does well.

I often had a hard time finding rear caps with a collar/flare for A, F, FA lenses. Now I found some at ebay.
I'll try to put PKA caps (with a collar/flare) on all my Pentax lenses. When I change lenses I take the one from the "new" lens and put it on to the one I just took off the camera. So, I want caps with a collar on all my Pentax lenses, to avoid mixing up those with a collar and those without.
This ebay guy has them: americaneagle_camera
