4.4 0.71x Focal Reducer Booster
The built-in optical correction group reduces the focal length of the attached lens by 0.71x and increases the aperture by 1 stop. This allows for a wider field of view and improved low-light performance. To calculate the approximate equivalent focal length for an M4/3 camera, shorten the lens's focal length by 0.71 and then multiply by the M4/3 conversion rate.
