Sigma 18-50 F2.8-4 DC OS HSM Lens:
R 2 399.00
Large Aperture, Standard Zoom with Optical Stabilization...
An upgrade to its predecessor, the 18-50mm F2.8-4.5 DC OS HSM is a lens
dedicated to digital SLR cameras with APS-C size image sensors offering a
large aperture and Sigma's Optical Stabilization.
Once again, Sigma has also engineered the built-in OS function, an
anti-shake system, (for Sony and Pentax mount) allowing the photographer
to see a stabilized image in the viewfinder. The combination of the large
aperture of F2.8 and anti-shake function makes capturing exceptional
photos in low light achievable, and the wide angle is wellsuited for
indoor photography.
Two SLD (Special Low Dispersion) glass elements and three Aspherical
lenses provide excellent correction for all types of aberrations. The
Super Multi-LayerCoating reduces flare and ghosting. Designed with inner
focusing and inner zooming systems, high image quality is assured
throughout the entire zoom range.
The overall length of the lens does not change during focusing and zooming
ensuring convenient handling. This lens has a minimum focusing distance of
11.8 inches (30cm) throughout the entire zoom range and a maximum
magnification ratioof 1:4.1. The incorporation of HSM (Hyper Sonic Motor)
ensures a quiet and high speed auto focus.
