Bikes in Snow

The first C-Mount to NEX adapter I received was used to make the NEX mount focusing helicoid, so I didn't have much of a chance to use it on actual lenses.  Received two more couple days ago that I ordered last week from a US vendor.  Tried various c-mount lenses on the NEX, and as expected, most wide angle lenses (less than 50mm) have severe vignetting.  Even longer lenses, some of them also have dark corners.  Most disappointingly, the Kern-Paillard Switar 50mm f1.4 still does not fit, and thus can not be focused to infinity, at least with the adapter I have.  Perhaps I can understand why.  The center ring was purposely made to mate with m42 mount lenses on this adapter.  So, in theory, you can use M42 lenses with this adapter if you add enough extension tubes.  More importantly, M42 mount focusing helicoids can be mounted to this adapter.  This will open up some opportunities for experiments with some specialty lenses.
