The SIGMA 18-250mm F3.5-6.3 DC OS HSM Lens, incorporates Sigma’s original
anti-shake compensation function, with a 13.8 times zoom ratio. As
opposed to having an anti-shake function in the camera body, this
lens’s Hybrid Optical Stabilizer provides not only an anti-shake
function for the camera body, but also compensates for image shaking in
the view finder as the Optical Stabilizer is built in to the lens.
Incorporating four Special Low Dispersion glass elements and three
aspherical lens elements provides excellent image quality throughout
the entire zoom range.
This lens has a minimum focusing distance of
45cm (17.7 inches) at all focal lengths and a maximum magnification of
1: 3.4 reproduction ratio, making it ideal for close-up photography.
An
inner focusing system eliminates front lens rotation, making it
suitable for use with circular polarizing filters and the supplied
petal-type hood.
Incorporating super multi-layer coating reduce the
ghost in the backlight photography. |
