Tripod mount

[tgr141291]

Hi all,

I have a canon 200m L f/2.8 lens and a Canon EOS 400D. Last week I borught a Canon 2x extender.

I've noticed that its getting a little heavy for the camera and was womdering if anyone could recomend me a tripod mount that would fit.

Links and reviews would be appricated

Many thanks in advance

Tom
