Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras.
The large aperture wide-angle lens for close up photography.
This large-aperture wide-angle lens is equipped macro focusing capability with a maximum magnification of 1:2.7 and fast F1.8 maximum aperture. The use of aspherical lenses are offered for superior peripheral brightness and compensation of aberrations and astigmatism. This is an ideal DG lens for Digital SLR cameras.
Macro capability
This lens is capable of Macro photography at minimum focusing down to 18cm (7.1 inch) (reproduction ratio 1:2.7). It incorporates the floating focus system in order to minimize distortion, spherical aberration and astigmatism, which provide high performance at all shooting distance down to 18 cm (7.1 inch). Reproduction ratio 1:2.7 and an angle of view of 84.1allow capturing of high quality images not only a subject but also the surrounding scenery.
Large front element and Super wide-angle
This lens has an advanced optical construction, in order to obtain adequate peripheral brightness at open aperture. Also, the iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background.
Handling
This lens also incorporates a Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. Also this allows the use of a "Petal-type Hood" , which is superior light blocking effect.
Aspherical lens
It incorporates a floating focus system and uses two aspherical lens elements for minimizing distortion, spherical aberration and astigmatism.
