Comments about Sigma Sigma 18mm - 200mm f/3.5-6.3 DC OS Autofocus Aspherical Zoom Lens for Nikon Digital SLR Cameras:

I purchased this lense used and I will never do that again as it has never worked properly! I bought the warranty with it and they had it for almost three months and were not able to fix it! I was told to send it back again, but I kind of feel like "whats the point"? I am super disappointed with my purchase! I have bought refurbished goods with no problems however and think this would be an awesome lense were it working properly!

I bought this lens along with a Nikon D50 body when the camera first came out. This lens and the camera, along with a small holster pack, has accompanied me on several trips and endured a short season of sports shooting during the two years I have owned it.

In strong light, it holds its own with Nikon's own lenses and is (reportedly) superior to Nikon's own 18-200 lens (non-VR variety). In softer light it doesn't seem to have Nikon's contrast...but can be punched up in post-processing as the lens itself is quite sharp. In fact surprisingly so all the way out to 200mm (I have now run tests against the Sigma 70-300APO and the Nikon 80-200 ED IF),

The lens is smooth and "positive" in action and as an all round lens, is hard to better except for not having vibration control. It obviously lacks the speed and contrast of lenses in the $1000 plus range, but otherwise holds its own.

completely satisfies what I need in a lense at a great price.

Over all this is a good lens. I shoot landscape and automotbiles. I shoot primes for cars, but this does purdy good in the field. I've not tried Nikons 18-200 (hard to get) but reading the reviews made me decide that type of zoom would be a good option to have a walking around lens. Ran 382 frames through two weeks ago at Red Rock, Valley of Fire and Zion. Good overall, though the light was flat so I am not sure that is a good way to judge this lens.

Seems well built and everything has a good feel to it. I would say yes to a friend

The reason I did not give it 5 stars (only 4) was because there might be a lens out there that is better. I just don't know if there is one!
