Phillip Reeve It delivers a very fast aperture in a small package for only 369$/396€. As expected, from an technical point of view this lens isn’t very good. Off center sharpness at longer distances is shitty, sharpness in general is average at best and flare resistance and field curvature can be problematic. Nevertheless I really enjoy using this lens and if you work around its flaws it can deliver nice images with a special character.
