Sigma Lens Foot

I know this might sound a bit trivial. But, after hopefully sorting out my support issues for my K10D/Sigma 50-500 combination, has anyone notice that there is very slight movement between the lens and lens foot on the Sigma 50-500, no matter how tight the lock is.

I can't say I have to be honest. Once it is locked in place on my tripod it is locked in place, no movement to be seen.
I still use either a cable release or remote for taking the picture though when I can. Not always possible of course, and even then the pictures are generally sharp.

On mine you can feel very slight movement between the front of the foot and the lens when it’s locked onto the tripod/head.
Sorry I know it’s trivial but any movement on a distant subject could be noticeable.
I also use a remote were possible (pity mines just died)!

Absolutely no movement on mine. And it is not over tightened.

Thanks for the info Beachboy2, may take the foot of the lens and have a further look!
As I mentioned it is only very slight.
