Sigma AF 35mm f1.4 DG HSM (Pentax)

Designed specifically for full frame sensors, this high quality Sigma Prime lens also works well with APS-C sized sensors found in entry-level digital SLR’s. When mounted on an APS-C body the 35mm focal length is what is generally referred to as ‘normal’ or ‘standard’, meaning it gives you the same angle of view as the human eye, so your images have a natural perspective. The fast f1.4 aperture is useful for achieving selective focus and really highlighting the subject of your photo.
