I have no major problems with this lens. I used it at the Canon EOS 450D and am satisfied with the images of the last 500 photos. Granted a value of F3.5-F6.3 is not the ne plus ultra, but at a focal length of 18-250 mm, a quite good result. Those looking for better values, should remain at fixed focal lengths. I photograph exclusively in the manual programs and'm happy with the focus. It is fast and quiet. With a focal length of 250mm, however, you should have a steady hand and not just rely on the OS technology. The processing makes a good impression all around. The only drawback, the built-in flash is useless by the size of the lens, because it casts a shadow.
