Well, they would be useful to check if the measured vignetting might be linked to colour shift issues. I'm using a Voigtlander Ultron 28mm f2, and while the major issue is the vignetting, but there's also a light colour shift in the corners.



By the way, Sony seems to have improved their sensor performance with wide-angle rangefinder lenses on the Sony NEX-C3, according to this post: [url="http://www.fredmiranda.com/forum/topic/1030741/1#9793822"]http://www.fredmiran...30741/1#9793822[/url] It seems to have helped somewhat with the native E16mm lens, as seen here: [url="http://www.photoclubalpha.com/forum/viewtopic.php?p=58527#p58527"]http://www.photoclub...?p=58527#p58527[/url]



I can't wait to see if the NEX-7 will also continue on this path.

The color shift issue is there but it's nowhere as extreme as with the Voigtlander 12mm f/5.6 (of course). I've taken a few field image where you can spot traces.
