Description
Digital
Camera Lens
18-125mm f/3.5-5.6 DC
Specially
designed to suit the characteristics of digital SLR cameras, this compact
and lightweight lens is now a reality. This zoom lens was exclusively designed for use with digital Single-Lens
Reflex (SLR) cameras and has a 6.9:1 zoom ratio. The image circle is designed
to match the size of the image sensor of digital SLR cameras. From wide angle to telephoto, this new zoom lens can capture a wide range
of subjects. As there is no need to change lenses, there is no risk of
missing those great shots. This lens has a minimum focusing distance of
50cm (19.6in.) at all focal lengths and a maximum magnification of 1:5.3.
A distance scale on the focus ring makes the lens convenient and easy
to use.
A
lens specially designed to suit the characteristics of digital cameras
is now a reality
Sigma's vast experience has been gained over many years in the development
of advanced optical technology and film camera production. This experience
was crucial to the development of the SD9 and SD10 digital SLR cameras.
Sigma took digital characteristics into consideration when designing the
lens power layout and created the most suitable lens.
A Special Low Dispersion (SLD) lens and two aspherical glass elements
produce a high level of optical performance through the entire zoom range.
We used the most appropriate coating for digital products to reduce flare
and ghost, caused by digital SLR cameras and to produce the best color
balance.
The
advanced design has resulted in a compact and lightweight lens
A Special Low Dispersion (SLD) lens and two aspherical glass elements
produce a high level of optical performance throughout the entire zoom
range. The resulting design has produced a compact and lightweight lens
measuring just 77.7mm (3.1in.) in length and 70mm (2.8in.) in diameter,
with a weight of 385gr (13.6oz.) and filter size of just 62mm.
Inner
Focus System
The lens is equipped with an inner focusing system, which prevents the
front element from rotating making it particularly suitable for Petal
shaped `hoods and a circular polarizing filters.
Zoom
Lock
The lens is also equipped with a zoom lock that eliminates "zoom
creep" during transit.
