Since this lens covers a APSC field of view, if I mount it on a micro 4/3 sensor, what will the equivalent field of view be (top to bottom). Will it basically show me what a 100mm would show in full frame? Trying to decide if I need the 50mm or the 35mm version of this lens for
Asked by: seyi
On a Micro Four Thirds sensor the top to bottom field of view would match a 100mm lens on a full frame sensor. The 35mm lens would likewise match a 70mm on a full frame.
