I HAVE BEEN USING MY NEW LENS FOR WEEKS AND AND ALL I HAVE TO SAY ABOUT THEM IS THEIR "GREAT"!!! I'VE SHOT CLOSE-UPS AND DISTANCE (ONE WITH TWO BUCKS FIGHTING-HORNS LOCKED) AND THE IMAGES HAVE TURNED OUT SUPER. MY FRIEND HAS THE TWICE AS EXPENSIVE NIKON EQUIVALENT AND WE ARE SHOOTING PRETTY MUCH ON PAR. I AM USING THE NIKON D90 AND LOVING IT. MY ONLY CON ABOUT THE SIGMA IS THAT IT IS A LITTLE BULKIER LOOKING THAN HIS NIKON 18-200mm BUT THAT IS ONLY COSMETIC AND I CAN LIVE WITH THAT AND THE PRICE DIFFERENCE!!
GREAT SHOOTING TO YOU ALL!!! RR OF COLORADO
Rating: - $[...] cheaper, same specs as Nikon equivalent, that's too much value.
This is worth the trade down to Sigma, which has been making decent lenses for years. $[...] bucks, it's crazy insane not to buy. With the savings you could buy a decent tripod or the Nikon 50mm f/1.8D AF Nikkor Lens, excellent for low light and some lens filters. I read the reviews for this 18/200mm lens and too many people liked it for the value and quality and I agree. This is the best walking around lens especially at the zoo, you get the tight head shot or the wide shot. Best general lens, jack of all shots.

Great lens for the price... can't complain about this lens. I got it over the Nikon due to pricing, and I am satisfied. I haven't had any lens creep yet (which is pretty much the only thing that I am worried about) but I keep it locked whenever I'm not zooming around with it.
The OS is perfect allowing you to effectively shoot at 200mm... it eats up a little bit of extra battery, but definitely is working.
If you can afford it, go for the Nikon, but if you dont have the extra dough to throw around I would pick this up no sweat. Excellent walk around lens...
Rating: - Half the price but half the qaulity
This is the second Sigma Lens I've owned and the second one I've returned. Common to many Sigma lenses is zoom creep, inaccurate focus, and heaviness. The reason I give it 3 stars?? If you use your DSLR more for snapshots and need a huge zoom range this lens is a good alternative to carrying two lenses or spending $600 on the Canon equivilant. If you want your pictures to be in focus and have a lighter lens, smoother focus ring and have some extra money in your budget, go with a Canon lens
