Ricoh Imaging | Pentax DA* 50-135mm f/2.8 ED SDM Lens

For standard to medium long-range applications with the utmost level of sharpness, contrast and overall picture clarity, look no further. This fast lens, designed exclusively for PENTAX digital SLR cameras, is an outstanding combination of quality optical performance and speed.

A high-performance, telephoto zoom lens.

The tightly sealed, weather-resistant and dust-resistant construction enhances durability for use in both rainy and dusty conditions, making it the perfect companion for weather-resistant PENTAX DSLR bodies.

Three Extra-low Dispersion (ED) elements compensate for chromatic aberration. With ED glass and original lens coatings, this lens is superior in contrast, clarity and edge-to-edge sharpness.

PENTAX-original SP (Super Protect) coating repels dust, water and grease to keep your lens clean and image quality at its peak.

PENTAX-original Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.

The SDM focus system incorporated in this lens results in a smoother, quieter autofocusing operation using a built-in supersonic motor.

The focal length is equivalent to 76.5mm-207mm in the 35mm format.
