loves old lenses
a comparison of 32 manual lenses with focal lenghts of 50 to 58mm ( + Pentax FA43 ltd. an autofocus f1.9/43mm lens )
camera used Sony A7
takes with ISO 100, A mode, Auto WB in RAW from wide open every full stop through f8
imported in LR5, exported as jpeg without any editing
seen are full frames and 7 different 100% crops
made a dedicated flickr stream for it, here it is: https://www.flickr.com/photos/kuuanslenstests/collections/72157670921126335/
EDIT: someone took my test images and made comparison MUCH easier!
any part of the frame of 2 photos taken with any lens at any f stop can be compared directly: http://www.lenshunters.com/tests/a7-normal-lenses-test/
( though not all lenses are included yet some more may follow )
