With its weather-resistant construction, it’s versatile enough for all types of shooting conditions and subjects, including portrait, still life, low light photography and weddings.

Pentax smc DA 55mm 1.4 SDM Lens In more detail

This Pentax smc DA 55mm 1.4 SDM Lens features high resolution for sharp, crystal-clear images of subjects and a smoothly connected out-of-focus (bokeh) softness. This is a medium telephoto lens that is ideal for portraits. The lens uses Anomalous Dispersion Glass for reducing colour blurring and enabling images with high contrast and sharpness. It also uses the “Aero Bright Coating,” which features higher transmissivity than conventional coatings for delivering high image quality with unparalleled sharpness and a minimum of flare. The lens uses a round iris diaphragm for providing natural out-of-focus (bokeh) effect and has a dust-resistant and drip-proof construction. The AF system is for SDM (AF using internal lens ultrasonic motor) only.

Focal length equivalent to 84.5mm in 35mm film format

This is a medium telephoto single focal point lens equivalent to 84.5mm in the 35mm film format, and it includes a large aperture with an extremely bright open F value of 1.4. This lens is ideal for portrait and other photography.

Aero Bright Coating

The newly developed Aero Bright Coating provides exceptional reflection performance over a wide wavelength range. This enables a significantly higher transmissivity for a substantial reduction in flare and ghosting, which adversely affect imaging performance.

Natural, soft out-of-focus bokeh effect

The newest optical design and a round iris diaphragm (up to F2.8) were developed with special attention to providing a natural, soft out-of-focus (bokeh) effect with a shallow depth of field that is only possible with large aperture lenses.

Dust-resistant and drip-proof construction

The various lens components have been sealed for enabling a dust-resistant and drip-proof construction that prevents the entry of water and dust into the lens.

Quick-Shift Focus System

If you turn the focus ring after focusing by the AF, focusing instantly switches to the manual focus. This enables smooth focusing operations without the need for a switching operation.

SP (super protect) coating

A special coating is used on the front lens for repelling water and oils. This enables any water and oils on the lens to be easily removed for effective protection of the lens surface.

Design developed specifically for digital SLR cameras

This design has been optimised for digital image characteristics to minimise ghosting and flare. Also, the image circle is tailored specifically to the size of the imaging elements for allowing a compact, lightweight body size for a large aperture .
