Angle 24mm f/1.8 EX Aspherical DG DF Macro AF Lens
:: Brand New, 4
Year Sigma USA Warranty ::
This 24mm 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). The 9-bladed aperture diaphragm obtains beautiful,
circular out of focus characteristics. 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 created
to minimize light falloff (darkening of the image corners) at maximum aperture-a
big benefit particularly for digital cameras. Materials used in this lens are lead
and arsenic free ecological glass.

Lens Hood, Case, Strap, 1-Year Worldwide Warranty + 3-Year Extended USA Warranty
