Contax Zeiss LEX mount jiggle

[waefre]

I recently made the switch over from my Canon Fd lenses to some sweet Zeiss glass. For the longest time I didn't think there cold be that much difference between them but have to say I'm very pleased I made the switch. The one troubling issue that I have is that with my Letus Extreme the Contax mount is not rock solid and the lens tends to shift while rolling the focus which creates a jiggle in the image. I got this mount second hand and was wondering if this is just the way they are or if it's just an older version and they've improved upon them just like they did to the Canon and Nikon mounts. Any other Zeiss Contax users out there have any issues or solutions to this? Thanks

Letus used to have a really inferior Nikon mount which I think was based off the Chinese nikon extension tubes and had the same jiggle, but they created a new batch from scratch to replace them and they are rock solid. It can't be too hard to make a solid mount. I got a Contax to EOS mount for my DSLR for 30 bucks and it's rock solid.

So are there no other Letus+Zeiss contax owners out there who can tell me if a little play in the lens mount is the norm with the Letus?
