The SMC PENTAX-FA 645 45MM F2.8 is a moderately wide-angle lens. Rather than the standard 75mm, the 35mm format, with a focal equivalent of 35.5mm with a 63-degree angle, is popular for street and wedding photographers. A f/2.8 maximum aperture shows images brighter in the viewfinder and allows for low-light shooting without drastically increasing the ISO. Photographers have the chance to use higher speeds in standard lighting conditions and add tastefully-blurred backgrounds to images.
