Dispute having 5 lenses in my kit bag (12-22, 24-70, 24-105, 70-200, 70-300) for the last two years I've hired one of these as a walk about lens (no e
) to take abroad on holiday & got great results with it. For me the extra 3 mm at the wide end over the 18-200.
Look at these reviews
<<<15-85>>> and
<<<18-200>>> and you'll see that the 15-85 is both sharper and suffers less distortion wide open
Both have IS & I couldn't live with the softness of the longer lens
As always JMHO
