Just want to follow up on this and hope it will help others.

I just did not have too much fun with this lens with it turning around with the adapter. Taking some queues from what has been done by others on other forums, I decided to solve this issue once and for all.
Using a fine point correct pen (ie. liquid paper) I took a marking of where the lens met the locking pin of the camera body. Next I covered up the lens with paper and tape. Taking a needle file, I filed a notch into the lens where it meets the locking pin.

Problem solved!

With this done, the lens locks securely and does not become loose with any adjustments on the focus and/or aperture rings. I'm just starting to get happy learning about the lens.
