## Long description

The PENTAX smc FA 31mm f/1.8 AL Limited is a compact fixed‑focal‑length wide-angle lens designed for high image quality and precise construction. With a 31 mm focal length and a bright f/1.8 maximum aperture, this limited-series lens combines optical performance and a compact metal body finished in black, and includes a flower-shaped lens hood.
Advantages
The lens uses a 9-element, 7-group optical design including a glass-molded aspherical element to minimise aberrations and deliver sharp, high-contrast images even at the maximum aperture of f/1.8. Its fast aperture provides good low-light capability and depth-of-field control. The aluminium body ensures durable build quality while keeping weight low for comfortable handheld use.
Suitable for
 Street and documentary photography
 Environmental portraiture and group shots
 Low-light shooting and available-light events
 General travel and everyday photography

How to use
Attach the lens to a compatible Pentax camera body using the mount until it locks into place. Use the aperture ring or camera controls to set the desired aperture; for shallow depth of field and low-light work select wider apertures such as f/1.8, and stop down toward f/8–f/11 for increased depth of field and sharper edge-to-edge performance. Focus manually or with the camera’s autofocus system if available; the lens’s closest focusing distance is 0.3 m. Use the included flower-shaped hood to reduce stray light and maintain contrast.
Usage recommendations
For best results, combine the lens’s bright f/1.8 aperture with careful focusing at wide apertures for subject isolation, and stop down when shooting landscapes or scenes requiring greater depth of field. Regularly clean the front element and use the hood to protect against flare.
