NEW 18-50mm F3.5-5.6 DC
Compact - Lightweight zoom lenses designed to suit the characteristics of
digital cameras.
Sigma Corporation is
pleased to announce the launch of the new 18-50mm F3.5-5.6 DC. This zoom lens
was exclusively designed to suit the characteristics of digital SLR cameras. The
image circle was designed to match the size of the image sensors of digital SLR
cameras, and this produced a compact lens with a maximum diameter of 60mm
(2.3in.), overall length of 67.5mm (2.6in.) and weight of only 245gr (8.6
ounces). It has a variable angle of view of 69.3degree?`27.9degree.
The use of aspherical lenses provides correction for various aberrations
throughout the entire zoom range and produce high level of optical performance.
18-50mm F3.5-5.6 DC lens has a minimum focusing distance of 25cm (9.8in.) at all
focal lengths and is capable of macro photography with a maximum magnification
ratio of 1:3.5.
*Digital cameras having
image sensors larger than APS-C size, and 35mm cameras, should not be used with
these lenses. If such cameras are used, severe vignetting in the images may
result. * The angle of view varies depending on the camera the lens is mounted
on.
