I haven't seen any problems handheld or tripod mounted. I have an ETRS (not I) so I don't have mirror lockup.

It has been stated that the noise is the mirror moving out of the way, however, there is also a light trap in front of the film which needs to move away as well so this may well be contributing to the noise.

Yes. It was designed to take pictures either handheld or on a 'normal' tripod. Try it that way and see if it works.
