Had an S2 and loved the pics , but wow what a noise . Have a number of Kowa's , definitely quieter than the Bronica . I'm not so sure the
Super 66 advance mechanism is really superior to the earlier Six . Both advances in my 2 Super 66's needed repair ( no easy task ) , where
as my much older Six has worked just fine . As has been said many times , refrain from frame advancing using the extended crank and force nothing
if it binds . Somewhere ( if you want ) I have pictures of the advance mechanism . I like the exchangeable backs on the Super 66 , but they too
have quite the counting and advancing mechanism . Do not try to remove lenses or backs without the camera being cocked . The 6MM are
rather more scarce and pricey . My rant , and yes I love 'em ! Peter
