Macro capability
This lens is capable of Macro photography, with minimum shooting distance of 20cm (reproduction ratio 1 : 2.9) and angle of view is 75.4. You can take picture not only the subject but also the surrounding scenery.
Large front element and Super wide-angle
The lens has an advanced optical construction, in order to obtain adequate peripheral brightness with open aperture. Also, the iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background.
Handling
The lens 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 also allows the use of a Petal-type Hood and the easy use of a polarizing filter.
Aspherical lens
It incorporates a floating focus system and uses two aspherical lens elements for minimizing distortion, aberration and astigmatism.
