I have read a lot of posted material about the Hologon and the alternative choices, such as the Leica 21/3.4 or the CV 15/4.5 III. It seems that the Hologon will give a "vintage look", and while some swear by its lack of distortion, others recommend not to buy it. I am curious about this lens, and I want to try it and see if I like using it.
