Sigma 28mm F1.8 EX DG ASPHERICAL MACRO Lens The large aperture wide-angle lens for digital and 35mm film SLR cameras. This lens has a macro focusing capability with fast F1.8 maximum aperture, which is ideal for Digital SLR cameras. Macro capability 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.
