Greetings,
I don't know if You were interested but I wished to share with all of You Cornerfix profile for my favorite Hologon with NEX-7. I don't know if You have already heard about CornerFix software and problem with symmetrical wide angle lenses and digital sensors. Due to short back focal distance this type of lenses were always limited to mirrorless cameras (mainly rangefinder of previous days). More information about it You may find in monography of Carl Zeiss wide angle's lenses by Dr Nasse ([url]http://blogs.zeiss.com/photo/en/wp-content/uploads/2011/12/en_CLB41_Nasse_LensNames_Distagon.pdf).
Profile's photo before and after processing with Cornerfix You may find here:

I made many trials to create this profile and finally I believe that results have been already acceptable. You may download it here:

(I don't know how to share other files than jpg, so You I may paste it inline: )

I know that this topic may be useful for narrow part of NEX-7 users but maybe You get interested. I read from Dr Nasse article that Hologon comes back with digital sensors is hardly imaginable. I hope my effort could change it, at last a little.
Best regards, WZ.
