SIGMA 24mm F1.8 EX DG ASPHERICAL MACRO for Sony

Thanks to its design, this EX range wide-angle prime lens, produced by the well-known Japanese company Sigma, is ideal for photographing architecture, landscapes and interiors. However, it is equally as good for shooting a photo report. The dual focus system makes it a breeze to work with. The rear lens is equipped with a Super Multi Layer (SML) of anti-reflective coating which serves to minimize light reflections from the sensor. It has excellent luminosity and fantastic contrast even with the maximum aperture setting.
Designed for digital SLRs with a sensor the size of a classic 35mm frame. The lens has a fixed focal length of 24mm and a luminostiy of  f/1.8. Aspherical segments are included in the design in order to eliminate colour aberration and image distortion. It is also equipped with a macro switch, making autofocus more effective in the regular photography mode.
