Sony NEX 5 with f5.6 12mm Heliar

the first set of testing this Voigtlander Heliar 12mm. f5.6 ASPH II. on Sony NEX  5
(the others lens will follow)

updated today (17.04.2011)  in Museum Siam in Bangkok., shoot wide open.

All it shoot with wide open handheld.

For me this lens is very sharp at wide open and not so much vignette as ever heard,
please feel free to comment, thanks.
