SIGMA 85mm F1.4 EX DG HSM Pentax

This sophisticated EX class lens from the Japanese company Sigma is perfect for portraiture.

The rear lens employs a Super Multi Layer (SML) antireflective layer, which minimizes reflections from the sensor. It has excellent brightness and contrast even at maximum aperture setting.

The lens is designed for classic 35mm digital SLR camera bodies. The lens has a fixed focal length of 85mm and a maximum aperture of f/1.4.
