About the Pentax 55mm F/1.4

High performance standard lens - large maximum aperture

With super-low-dispersion optical elements, extra-low dispersion (ED) optical elements and PENTAX original lens coatings, the PENTAX DA* 55mm F1.4 SDM lens assures outstanding image quality with clear, high-contrast images, even at image field edges.

It features water and dust resistant sealing for reliable operation in inclement conditions, and the PENTAX Quick-Shift Focus system to allow instant auto-to-manual focus switching. Objective lens surface is treated with PENTAX original Super Protect (SP) coating. This special fluorine compound is applied through a vapor deposition process to create a surface that effectively repels dust, water and grease.

It also features a new Aero Bright coating for maximum light transmission, and rounded diaphragm blades to create a more circular aperture for smooth, beautiful bokeh at large apertures.
