Pentax FA 28-105mm f3.5-5.6 ED DC WR Lens

The HD Pentax-D FA 28-105mm f3.5-5.6 ED DC WR lens is a compact, lightweight standard zoom lens providing a focal-length range from wide angle to medium telephoto. Despite its compact, highly manoeuverable body, this versatile zoom lens is designed to accommodate the image circle of a large 35mmfull-frame image sensor, thanks to the adoption of state-of-the-art optics and high-performance optical elements.

Standard zoom lens covering most frequently used ranges
This standard zoom lens accommodates the image circle of a 35mm full-frame image sensor, and covers focal lengths between 28mm wide angle and 105mm medium telephoto. By incorporating the latest optics and a number of high-performance optical elements, it retains a sufficient brightness level even at edges of the image field, while effectively compensating for various aberrations. It delivers high-resolution images by optimising the imaging power of the Pentax K-1’s (approximately) 36.4 effective megapixels. Its compact, lightweight body and excellent cost performance make this lens an ideal regular lens for the Pentax K-1.

Superb image quality
In its 15-element, 11-group optics, this zoom lens incorporates two high-precision aspherical optical elements, one ED (Extra-low Dispersion) glass optical element and one anomalous-dispersion glass optical element, to deliver bright, sharp images with minimal chromatic and spherical aberrations. Since its optics are designed to assure ample resolving power for the large, high-pixel image sensor, it produces well-defined, fine-detailed images.

HD Coating
This lens is treated with the high-grade, multi-layer HD Coating. Compared with conventional multi-layer coatings, this Pentax-original coating assures higher light transmittance and less reflection to deliver bright, high-contrast images that are free of flare and ghost images, even under demanding lighting conditions including backlight.

Quick-Shift Focus System
This Pentax-developed system allows for flawless, delay-free switching from autofocus to manual-focus operation, after the subject is captured in focus by the camera’s AF system.

Weather-resistant
This lens features a dependable weather-resistant construction with eight sealing parts to effectively prevent the intrusion of water into the lens interior. Paired with a weather-resistant Pentax DSLR camera body, it creates a durable, dependable digital imaging system that performs superbly in demanding shooting settings —even in rain or mist, or in locations prone to water splashing or spray.

Additional features

• SP (Super Protect) Coating applied to the front surface of the lens to effectively repel water and grease
• Rounded diaphragm to produce a smooth, beautiful bokeh (defocus) effect, while minimising the streaking effect of point light sources
• Built-in DC motor to assure smooth, quiet, high-speed autofocus operation
