Well, this is pretty cool. A reverse lens mount adapter for Sony that you can actually autofocus with. Designed for the Sony E-Mount cmaeras, including the A7 series, A9 series and APS-C format A6000 series, the new NEX-Retro from Novoflex lets you turn any Sony lens into a macro.
Being able to reverse a lens on a body isn’t a new idea, but what’s special about this one is that passes along all of the electronic functions. This means you get full control over aperture and autofocus from the reversed lens as if it were mounted normally. It’ll even pass along the EXIF data.
