Many a photographer is looking for a long lens that the widest possible zoom range covering without causing visible quality impacts. Over a longer time I have favored Zuiko 50-200 mm; the high price and the heavy weight made the choice - as a compromise - on the next flights as hand lens fall 18-180mm. The product is highly processed with value and clean. The Zoom runs easily and smoothly. The light intensity is sufficient for most applications; even when shooting indoors with flash support the optics shows unexpected application qualities. Meanwhile, it is the "daily use" something like a look for - almost - become all cases. The imaging performance is - how it is geohnt of Zuiko lenses - impeccable. Also as used product a very good buy.
