Sigma EX wide-angle lens - 28 mm

• Manufacturer: SIGMA
• Part number: 440-101
• Description: This lens has a macro focusing capability with fast F1.8 maximum aperture, which is ideal for Digital SLR cameras. This lens is capable of Macro photography, with minimum shooting distance of 20cm (7.8 inch) (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. 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. 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. It incorporates a floating focus system and uses two aspherical lens elements for minimizing distortion, aberration and astigmatism.
