Hmmm, out of curiousity, has anyone seen if a Pentax 6x7 will do the mirror prefire? I know that they usually have MLU, but it might be interesting if, like the Spotties and other mechanical Pentaxes, they can do it.

Re: the $750 Spotties with MLU, I think I'll stick with my $5.00 black Spottie with the mirror prefire feature.
