Not only at close range, and long range, the lens offers excellent sharpness and good resolution over the entire image area. A chromatic aberration (color fringing) is not to be recognized, vignetting (vignetting) not also.
All in all a great lens. Unfortunately, only a fixed focal length. A 3x zoom with these imaging characteristics would certainly be all the rage.
So just for specialists? In principle, yes. But a must for all those who want up close to the object, so that want to exploit the macro-properties of this lens.
Who needs only a good fixed focal length lens, which can also access the "Canon EF 50mm 1.8 II". The costs almost only a quarter and has also very good imaging properties. But there's just no macro. The minimum focusing distance is "only" 45 cm.
When "Canon 60mm 2.8" is the minimum focus distance 20 cm, however. Not such a big difference? Wrong! This distance, by referring to the image plane (indicated by a mark on the camera body). The minimum distance from the front of the lens to the object is therefore the 50mm lens about 35 cm and at 60mm about 8 cm.
My vote for the "Canon EF-S 60mm 2.8 USM Macro": full 5 stars.
