Lens Description

The Pentax FA 50mm F1.4 is a normal prime designed for cameras with a Full-Frame sensor. This ultra-bright prime has a 50mm focal-length.

This prime can focus down to 45cm from the imaging plane which gives it a maximum magnification of 0.15X. The lens can focus automtically with the Focus-Drive selected by the camera. While this lens is capable of AF, it does not have a built-in focus motor. It can only focus with a compatible camera body which features a mechanical AF-coupling.

This lens is only available for Pentax K. Follow this link for all current compatible digital cameras: Pentax K mount cameras with Full-Frame or smaller sensors.
