Sony A7 vs Leica Zeiss Voigtlander Rangefinder Lenses

TechTalk on the Sony A7

TechTalk with Ron Scheffler is currently posting its Sony A7 torture test. The A7 was a pre-production unit so the results may differ from the final product. The number of lenses tested in 1.5 hrs is staggering. The big question for those looking to get the new full frame Sony A7 is, "Does it play well with rangefinder lenses?" Ron tested the heavyweight of the RF lens world from Leica, Carl Zeiss, Voigtlander. Here is the list of lenses tested.
