Product Highlights
  • For Olympus Digital Cameras (Four Thirds System)

The Sigma 24mm f/1.8 EX Aspherical DG DF Macro Lens has a fast f/1.8 maximum aperture with macro focusing capability (minimum focusing distance is 7.1" for a reproduction ratio of 1:2.7). It incorporates a floating focus system and uses two aspherical elements for minimized distortion, spherical aberration and astigmatism. The lens front does not rotate during focusing, thus allowing the use of a "perfect hood" and the easy polarizing filters. Optical construction was designed to minimize light falloff (darkening of the image corners) at maximum aperture - a big benefit particularly for digital cameras.

The improved DG lens design for this lens corrects for various aberrations. This macro lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.

Note! Not suitable for 35mm film SLR cameras.

This lens provides an equivalent range of 48mm when used with an Olympus digital SLR camera.
The 9-bladed aperture diaphragm obtains beautiful, circular out of focus characteristics.
Materials used in this lens are lead and arsenic free ecological glass.
