Sigma 20mm F1.8 EX DG Aspherical RF (Sony)

The Sigma 20mm F1.8 EX DG Aspherical RF is a wide angle lens offering a 94.5 degree angle of view. The large f/1.8 maximum aperture offers shallow depth of field as well as being able to pull plenty of light into your shots. This helps to make the 20mm F1.8 EX DG Aspherical RF a good choice if you are working in fading light. It can also allow you to hand hold the lens when taking shots indoors.

A petal type lens hood is supplied with the lens by Sigma. This helps to reduce any issues caused by lens flare.
