Zoom lens that
is designed to suit the characteristics of digital cameras.
Exclusively designed to suit the
characteristics of digital SLR cameras. The image circle was designed to
match the size of the image sensors of most digital SLR cameras and this
has resulted in a compact lightweight lens. The use of aspherical lenses
provides correction for various aberrations and makes high quality
images a reality throughout the entire zoom range.

Exclusively
designed to suit the characteristics of digital SLR cameras.
We took digital characteristics into
consideration when designing the lens power layout and created the most
suitable lens that makes high quality images a reality throughout the
entire zoom range. We used the most appropriate coating for digital
products to cut down flare and ghost caused by digital SLR cameras and
to produce the best color balance. It can be used with the supplied lens
hood to block out extraneous light.
