You can correct distortion caused by fisheye lenses to give photos the appearance of pictures taken with a wide-angle lens.
You can preview the effects of fisheye compensation in live view during shooting. The camera corrects the distortion caused by the lens, and then crops the picture to eliminate blacked-out areas. This feature is available only with compatible fisheye lenses. （M.ZUIKO DIGITAL ED 8mm Fisheye PRO）
