Mounts EF lenses to E-mount cameras but with some magical glass that emulates the Super Baltar lenses that brought us the Godfather Part I and II, Hitchcock’s “Birds”. It works best on fast lenses. Autofocus does pass through so using these with something like Sigma Art primes is such a quick and cheap hack to make “cinematic” images on the cheap with a one man band setup. They look rad with the cheap Samyangs.
