Sigma 18-200 mm F3.5-6.3 DC OS
Photokina 2006: Sigma has announced another digital-only lens, the new 18-200 mm F3.5-6.3 DC OS lens. This compact lens offers a big 11x zoom range in combination with Sigma's own Optical Stabilizer. Just like the 18-50 mm DC lens this one features aspherical and low dispersion elements as well as multi-layer coating to reduce flare and ghosting. On the downside it is slow (F6.3) at telephoto (you can't have everything at this price). On a digital SLR with a 1.5x FOV multiplier this lens provides an equivalent field of view of 27-300 mm on a 35 mm camera.

- Equipped with Sigma’s own unique technology OS (Optical Stabilizer) function.
- Two SLD (Special Low Dispersion) glass elements and two aspherical lenses provide excellent correction for all types of optical aberrations.
