A nice enough lens to use but the very long throw of the lens does slow you down a lot. To get to one ned of the manual focus end to the other I'm very nearly turning that ring about 360 degrees. It's the one caveat of this lens, otherwise it's nice enough. Can I recomend it? Well yes, but there are a few better 50mm lenses out there, the Zeiss Planar 50 f2 for one which performs exceptionally well on the Sony A7. It is dearer however so if money is a problem, go for this one.
