• Fast F1.8 maximum aperture for shallow depth of field and cropping flexibility.
• Delicate bokeh when stopped down to approximately F4, matching portrait needs.
• Optimized correction of chromatic aberrations to reproduce fine details like hair.
• PENTAX-original HD coating and a round-shaped diaphragm for enhanced imaging quality.
• Extendible, built-in lens hood for straightforward light-shielding and compact storage.

Optical performance and image character

The lens uses coatings and optical design to control spherical aberration across different wavelengths, which helps minimize color bleeding. In addition, the interior of the lens barrel receives a highly efficient black coating to greatly reduce internal reflections. As a result, the lens reproduces delicate tonal variations—especially in white subjects—and clearly renders the brightest spots in highlight areas.

Aperture behavior and use cases

At larger apertures near wide open, the PENTAX-FA HD 77mm F1.8 Limited performs especially well for portraiture and quick snapshots of people. It faithfully renders subtle facial nuances and tends to produce distinctive, warm colors that suit human subjects. Conversely, when you stop the lens down to smaller apertures, you can increase overall sharpness and exercise greater control over the ambience of the captured image.

Design details that matter

The lens retains the distinctive optical performance of the smc PENTAX-FA 77mm F1.8 Limited while adding PENTAX’s HD coating and a round-shaped diaphragm. These refinements contribute to what Pentax describes as exceptional imaging power. Furthermore, the extendible lens hood is built into the barrel to simplify both light-shielding during shooting and compact storage when not in use.

Who will appreciate this lens?

Photographers who prioritize portrait work will find this lens well matched to their needs. In addition, Pentax expects this model to remain a favorite for many years in both digital and film photography, making it suitable for users who shoot across formats.
