Pentax smc A 50mm f/1.2

Pentax smc A 50mm f/1.2 lens

Full frame sized image

Lenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either.


No stepping motor AF

Lenses with stepping motor focusing mechanism are better for contrast based focusing, and are quiter and faster than traditionally focusing lenses.


No Low Dispersion lens element is used

Low Dispersion lens elements help to reduce chromatic aberration.


Not stabilized

Image stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule.

The PENTAX smc P-A 50mm F1.2 is a faster lens with a larger aperture opening. It is ideally suited for photography in low-light situations and its natural perspective of subjects makes it ideally suited for everyday use including indoor photography, traveling, and hiking. Like every PENTAX lens, the smc P-A 50mm F1.2 lens features our acclaimed smc multi-layer coating to lower surface reflection, reduce ultraviolet rays, and deliver clear, high-contrast images.
