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 magnif
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.
