Mounted on a Canon 600D case this zoom amazed me with the quality of images provided even at the maximum focal length of 250mm. Of course we should stop down to F: 8 for maximum sharpness. But the picture is crisp and the center and even the banks are more than good. The minimum focusing 35 cm zoom back allows to make beautiful things in close-up photography with a rather nice bokeh. The objective is well built and is lightweight and compact.
4 stars ....... because for much more expensive there is better of course !! But an excellent quality / price ratio.
