Have the lens since about 2 months and have to say that there are great photos there macht.Gut has no stability but if you observe a few things such as the shutter speed then it nice sharp images no matter if 28mm or 200mm and no other artifacts (darkening of the corners or the distortions) A little tip for all who make photos without stabilizer which are often out of focus, you take the focal length times the crop factor results in the time that you can hold without problems. (100mm focal length x 1.6 in Canon gives 1/160 second) simply hope the tip will help you not only with this lens. Regards Robin
