Full Frame X-Pro1? - The Mitakon Lens Turbo Review | Jonas Rask | Fuji X-Pro1 | Scoop.it


As soon as I heard that the good folks at Mitakon were making a Metabones Speedbooster equivalent, I was part sceptical, part thrilled. I mean, this isn’t just your usual “tube” adapter. This actually has a piece of glass inside. So, no doubt would the chinese Lens Turbo be cheap, but would it also be of acceptable quality? For starters let me explain a little bit of theory behind how these adapters work. The adapter mounts between the old SLR lenses and the X-Pro1. It makes the lens wider by a factor of 0.71x, sort of like an “inversed” tele converter. Like the effect of a magnifying glass, it also concentrates the light. This gives a full stop of extra light. So an  f/2.0 lens gathers light of an f/ 1.4 lens. So if you mount a Minolta full frame lens on the X-Pro1, it will have the same angle of view and the same depth of field as a full frame camera.  A 50mm no longer acts like a 75mm, but like a 50. A 21 like a 21… you get the point......
