HD PENTAX-FA 77mmF1.8 Limited
This medium telephoto lens has, in addition to the focal length, features that make it a perfect portrait lens.
At wider apertures near the open aperture, the lens is ideal for portraits or snapshots of people, as it faithfully reproduces the subtle nuances of the subject and produces distinctive warm colours. At smaller apertures, photographers can enhance sharpness and even control the atmosphere of captured images.
Inheriting the distinctive optical performance of the smc PENTAX-FA 77 mm F1.8 Limited, this lens offers exceptional imaging performance, made possible by PENTAX's meticulous attention to details that cannot be easily measured by numerical factors. An important criterion here is the excellent reproduction of warm colours, which is particularly important for portraits or snapshots of people to create that unique look.
The lens features a coating that effectively controls spherical aberration at different wavelengths to minimise colour fringing, while internal reflections are greatly reduced by applying the most efficient black coating possible to the inside of the lens barrel. It is designed to faithfully reproduce delicate shades in white subjects and clearly show the brightest point in the brightest areas.
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.
Exclusively designed lens hoods and slip-on caps to match the character of individual lenses
The lens hood makes the lens easier to store and is ready for use as soon as you remove the cap from the front end of the lens. The lens hood is shaped to optimise the optical performance of the lens. The inside of the lens hood has been electrostatically flocked to minimise internal reflection and attract dust particles, preventing them from sticking to the front of the lens.
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.
Features / Specifications
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.

Comparison of dirt adhesion (oil-based ink)
A lens surface treated with SP Coating has a very smooth surface without the adhesion of the oil-based ink.
|
Comparison of wipe-off (oil-based ink)
A lens surface treated with SP Coating can be wiped clean more easily and completely, even after the ink has dried.

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.
Lens Hood included
In addition to a variety of features, such as our unique HD coating and the elimination of reflections in the lens barrel, a retractable lens hood is integrated into the lens barrel. It has been designed to optimise light shielding and storage. The lens hood is an integral part of the optical system and should always be used when the lens is in use.
Others
1. Rounded diaphragm This lens features a completely round-shaped diaphragm, which produces a natural, beautiful bokeh (defocus) effect in the images captured, while optimizing the imaging performance of the distinctive Limited-series optics contained within.
2. Quick-Shift Focus System which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera’s AF system.
