HD PENTAX-FA 31mmF1.8 Limited

An exceptional lens that delivers the sharp, high-contrast, well-defined images that faithfully depict the ambience of the scene

Image to render

This lens has a focal length of 31mm, which is approximately midway between the conventional 28mm and 35mm wide-angle lenses. This unique focal length draws out the best visual effect of each conventional focal length, depending on the way an image is framed.

It features glass-molded, aspherical elements and high-refraction, low-dispersion glass elements to define the main product concept — a lens that delivers sharp, fine-detailed images of small subjects.

A lens, making you photography more enjoyable

Machined aluminum lens barrel to optimize the texture of the material

Every lens barrel and all exterior components of the PENTAX Limited-series lenses are meticulously machined from high-grade aluminum material to optimize the high-quality visual design and the feel when the photographer touches them.
Their elegant shape and distinctive appearance are still loved by many camera enthusiasts today, even as the format of most camera bodies has shifted from analogue to digital.

A large aperture and a compact, lightweight design

Under today’s standards, large-aperture lenses are expected to be so heavy and bulky because designers try to optimize resolving power and contrast while minimizing various aberrations. With FA Limited-series lenses, however, PENTAX has succeeded in achieving these two contradicting goals simultaneously, by making them compact and easy-to-handle through effective control of aberrations, while optimizing the sense of depth and sharpness in resulting images. Because these lenses deliver image descriptions that truthfully convey the ambience of the image, and also provide the flexibility to change the visual expression with different aperture settings, they are still greatly appreciated by many photographers as truly special lenses.

HD Coating to enhance imaging performance

The lens incorporates the PENTAX-developed, multi-layer HD (High Definition) Coating. Compared with conventional multi-layer coatings, it improves light transmittance while reducing average reflectance in the visible ray spectrum. This means that it can deliver clear, well-defined images with minimal flare and ghost images, even under demanding lighting conditions such as backlighting.

SP Coating

SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.

PENTAX K Mount

The lens mounts for PENTAX interchangeable lenses are based on the bayonet K mount, which has remained unchanged since its inception in 1975. It is a mount unique to PENTAX that features a large aperture combined with superior ease of replacement, accuracy, and toughness. These features are utilized to comfortably incorporate an iris control mechanism, autofocus mechanism, and other functions for enabling nearly complete compatibility with conventional lenses. The PENTAX K Mount keeps its advanced versatility despite differences in camera and lens functions.

In addition, this lens is equipped with an aperture ring, which means that it can also be used on older cameras without electronic aperture control without any restrictions.

Integrated lens hood and slip-on cap to match the character of individual lenses

The integrated lens hood is part of the optical system, and also lets you start photographing immediately simply by removing the cap from the front end of the lens. This lens hood is shaped to optimize the optical performance of the lens. Electrostatic flocking has been applied to the inside of the lens hood to minimize internal reflection, and also to attract dust particles and prevent them from sticking to the front surface of the lens.

Others

Quick-Shift Focus System
After focusing using the autofocus, the focus ring can be turned to allow immediate focus adjustment using the manual focus.
This feature enables smooth operability by eliminating the need for an AF/MF switching operation. This is useful during closeup photography, for instance, when you want to shoot while making fine adjustments to the focus

Rounded diaphragm
to produce a smooth, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources (Rounded diaphragm F1.8-F3.5）
