Shot with the Sony A7s, currently my favorite camera for everything,
and the Avenon MC L 3.5 28mm,
camera setup after the break
Sweet, very small, almost a pancake, very sharp in the center at 5.6 and 8, decent boarders, the only draw back, close focusing is rather pathetic.
A great mf lens.
You can find pretty good deals on that lens, some patience might be required.
