10 out of 10 points and recommendedVery sharp, excellent IQ, a good travel and walk around lens, not too heavyLens hood sold separately, cannot adjust the zoom ring when lens hood is reveresly attached
This is my upgrade from the 18-200 Sigma lens using a 500D body and a battery grip. At daytime, the lens is fast and very sharp. At night time or low light, you have to adjust the ISO or Shutter speed to get a fast and decent images. Looks and feel sturdy, not too heavy, a good partner with a prime lens 85mm or a telephoto 70-300mm for far distance subjects.reviewed January 13th, 2012 (purchased for $1,200)
You'll never regret having this lens for your day-to-day or walkround lens on an APS-C body (take note the quality is far better than the kit lens).
