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: http://www.fredmiranda.com/forum/topic/1.../1#9793822 It seems to have helped somewhat with the native E16mm lens, as seen here: http://www.photoclubalpha.com/forum/view...527#p58527
I can't wait to see if the NEX-7 will also continue on this path.
