Voigtlander has announced the VM-E Close Focus adapter, which will allow the use of M-mount lenses on Sony E-mount cameras such as the recently-announced full frame A7 and A7R. Unlike most similar adapters, though, Voigtlander’s latest includes a focusing helicoid for close-up work, with 4mm travel. This overcomes a limitation of many rangefinder lenses, which often have longer minimum focus distances than similar SLR lenses. It’s set to be available in December for €289.
