The Pentax DA* 55mm f/1.4 lens excels in delivering exceptional contrast, clarity, and edge-to-edge sharpness, thanks to its advanced construction utilizing extra-low-dispersion (ED) glass and proprietary lens coatings. With elements such as super-low-dispersion optical components and Pentax's original lens coatings, this lens produces remarkable high-contrast images, maintaining impressive detail right to the edges.

Engineered for dependable performance in adverse weather, the lens is equipped with a robust water and dust-resistant seal. It also features the Pentax Quick-Shift Focus system, allowing photographers to effortlessly switch between automatic and manual focusing modes. Additionally, the objective lens surface is treated with Pentax’s Super Protect (SP) coating, a unique fluorine compound that is applied via a vapor-deposition process. This innovative treatment provides a surface that effectively repels dust, water, and grease, ensuring that the lens remains clean and reliable under various shooting conditions.

A careful blend of specialized lens coatings, ideal optical element arrangement, and precise curvature work together to enhance the digital imaging characteristics of the Pentax DA* 55mm lens while minimizing issues such as flare and ghosting. The lens features an Aero Bright coating designed for maximum light transmission, which allows you to capture brighter and clearer images.

Also noteworthy are the nine rounded diaphragm blades that facilitate a more circular aperture shape, which contributes to producing a pleasing and smooth bokeh effect when using larger aperture settings. With a fast maximum aperture of f/1.4, it provides outstanding control over depth of field, making it an excellent choice for creative photography applications.

Additionally, the lens boasts a minimum focusing distance of just 1.48 feet, enabling close-up shots with impressive detail. Whether you're capturing portraits, still life, or working in low-light situations, this lens proves to be a versatile and reliable companion.
