Sigma Zoom Super Wide Angle 18-200mm f/3.5-6.3 DC Aspherical (IF) Lens for Pentax Digital SLR
The Sigma 18-200mm f/3.5-6.3 DC lens is specially optimized for digital SLR cameras, and offers an "all-in-one" super-zoom lens solution. This lens provides the equivalent focal range of approx. 27-300mm when used with a Pentax digital SLR camera(*).
It's design incorporates aspherical lenses and SLD (Special Low Dispersion) glass that provides the utmost correction for all types of aberrations and enables this extended super-zoom lens to be housed in a compact and lightweight construction.
DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is made to match the smaller dimensions used for the image sensor on digital cameras. As a result these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.
(*)Note: Not compatible with 35mm cameras or digital cameras using full-size image sensors.
- Super Multi Layer (SML) coating reduces ghost and flare
- Two pieces of Special Low Dispersion (SLD) elements and two hybrid aspherical lenses provide high quality images throughout the entire zoom range
- The lens design incorporates an inner focusing system, which prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods
- A magnification scale is displayed on the lens barrel for each focal length, ensuring ease of use

Comments about Sigma 18-200mm f/3.5-6.3 DC Lens for Pentax Digital SLR:
I wanted a lens that would replace my standard 18-55mm kit lens that wouldn't break the bank. The reason why i chose the sigma is due to the fact that it's a great bang for the buck- it's about an 11x zoom and it's very sharp. I also like how it's an internal focus so the petal hood that comes with the lens works perfectly with it. It's pretty darn compact and durable as well. My only issue with the lens is that at full zoom it's a 6.3 aperture which is slightly darker so you have to compensate a stop or 2. People complain about lens creep but i'm not running around like a lunatic... Overall, it's a compact, strong lens that's sharp as a tack and easy on the wallet!

Comments about Sigma 18-200mm f/3.5-6.3 DC Lens for Pentax Digital SLR:
I was very excited to get this lens. When it came I was not a happy camper. AF would work only in the wide angle. When I would zoom in on anything it would stick and not work. This was my first Sigma lens....so maybe it was just a fluke thing and I got a bad one. I sent it back for a refund.

Comments about Sigma 18-200mm f/3.5-6.3 DC Lens for Pentax Digital SLR:
This is my new all-purpose lens. The large zoom range is fantastic, greatly reducing the number of lens changes needed. This lens really makes my DSLR a lot more user-friendly. It seems to be well constructed and feels very solid and sturdy. Image quality is great. The specs say the minimum focus distance is 1.5' but mine focuses consistently at 7-8" from the end of the lens. Perhaps Sigma measures from the base of the lens? Of course, there is the usual distortion at the extreme wide end, and this is not a fast lens. However, this lens is a great value and is certainly acceptable at least for my needs. If you are looking for an everyday lens and your expectations are kept realistic, you could be very happy with this lens.

Comments about Sigma 18-200mm f/3.5-6.3 DC Lens for Pentax Digital SLR:
I own a great deal of lenses, zooms and primes included but bought this lens for the wide range of zoom. I just took in on a week vacation and it was ideal for a travels lens - wide to decent tele with a great pricetag. I would have given 5 stars for the purpose I bought it but gave it 4 because I think it could have been slightly faster but overall its a good lens for a good price.
