Sigma 24mm f 1.8 EX DG Aspherical Macro is one of the EX Series lenses. This lens has a fast F1.8 maximum aperture with macro focusing capability of minimum focusing down to 18cm/7.1inches (reproduction ratio 1: 2.7). The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus image. It incorporates the floating focus system & uses two aspherical lens elements for minimizing distortion & spherical aberration & astigmatism. Internal focus system eliminates front lens rotation, thus allowing the use of a Perfect Hood & the easy use of polarizing filters. The lens incorporates non-vignetting optical construction, in order to obtain adequate peripheral brightness even at open aperture. This is desirable for digital cameras. The lens also incorporates dual-focus mechanism. It is easy to hold the lens, since focusing ring does not rotate during auto-focus, & yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The lens materials used in this new lens are lead & arsenic free ecological glass. ...

With its wide angle view from 102.4 degrees it can produce striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting & it enables photographers to emphasize the subject. Two ELD glass elements & a SLD glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion & allow compact & lightweight construction. The super multi-layer coating reduces flare & ghosting. High image quality is assured throughout the entire zoom range. The incorporation of HSM ensures a quiet & high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 9.4 inches throughout the entire zoom range & a maximum magnification ratio of 1:6.6. The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood & polarizing filter. The petal-type hood blocks extraneous light & reduces internal reflection. ...
