Summary: As a landscape photographer, sharpness is irreplaceable. I am always on the look-out for a light lens that suits my backpacking and hiking needs - and this lens is not it! Realistically, I knew this lens would not perform like a prime lens or $1500 zoom lens.
Summary: I bought this lens for my Nikon SLR and was very disappointed. The lens did not fit the camera correctly (I would get f-- for the f-stop) so no picture could be taken. I called Sigma and they said the only way to fix it was to ship the lens back to Sigma.
Summary: I'm not sure if the lens that I got was just defective or representative of the product as a whole. I will say that this lens is in the process of being returned and replaced with another brand.
Summary: I purchased this as a lower cost alternative to the Sigma 18-250 for use on my Canon Xsi. Construction quality and optics seemed to be fine. The optical stabilization was something else completely.
Summary: I purchased this lens to attach to a Nikon D-60 SLR camera. It was to be used in my many excursions with a travel/exchange group. This year we went to Turkey. At first I was satisfied with the lens but it commenced to give me camera errors that read sort of," Lens not fully attached to camera".
Summary: Loved this lens when it worked... however now, only one year later, this lens doesn't work! Short circuits new Nikon D90 camera and won't AF on D50. I can't afford to be buying a new $500 lens on a yearly basis - I'm extremely disappointed in Sigma's longevity.
Summary: After my Sigma broke, I got a Tamron version with similar specs but at cheaper price and for better value. In all honesty, the 18-200mm has an issue of introducing noise, and the locking mechanism is very rigid so you are likely to get it jammed.
Summary: I thought that the other lenses that weren't Canon were of the same quality. Talked to many fotographers and all agreed. But NOT!! I get a much sharper picture with my original canon that with this Sigma lens. So...
