The smc PENTAX DA* 55mm F1.4 SDM is a high performance, compact, medium-telephoto lens offering a large
maximum aperture. With super-low-dispersion optical elements, extra-low dispersion (ED) optical elements
and PENTAX original lens coatings, this 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. The combination of special lens coatings, ideal curvature and
best positioning of optical elements assures optimized digital imaging characteristics, while effectively
minimizing flare/ghosting.
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. |
