Angle of view for micro four thirds prime lenses

0

Below is a table of angles of view at different focal lengths for Micro Four Thirds prime lenses. Thinking in angle of view is smart, as it makes it easier to know approximately how much you will get into the frame. A tool for measuring angles of the type you would use for a maths class might be helpful if you want to learn to previsualize the framing with a particular prime lens. The last column shows some of the prime lenses available for the MFT system by manufacturer and f-stop.
