PENTAX 21 /2.4 ED HD D FA LTD DC WR SILVER

Offered here in black, the PENTAX-D FA 21mm f/2.4ED Limited DC WR HD Lens from Pentax provides an ultra-wide field of view on full-frame K-mount DSLRs. landscapes, this lens gives you a sophisticated optical design for exceptional sharpness and even illumination. The wide 92° angle of view is well suited to panoramic shots both indoors and outdoors. When used for distant subjects such as landscapes, it ensures smooth, solid image reproduction across the entire image field and delivers sharp, clear, high-resolution images.

Contrasting the wide-angle, wide-angle perspective is a close-focus system that provides a minimum focusing distance of 7.1" along with a maximum magnification of 0.26x for working with close-up subjects. Its maximum aperture of f/2.4 allows you to work in low-light conditions.and also offers greater control over depth of field to isolate your subject.A rounded eight-blade diaphragm also contributes to a pleasing, smooth bokeh quality.This lens also features a high-quality HD coating for exceptional image reproduction, which controls ghosting and flare for high-contrast images with accurate, neutral color balance, plus an SP Protective Coating on the front lens surface to repel dust, stains and debris.In addition, the body, hood and lid are made of high quality aluminum,Meticulously machined for an attractive appearance and a beautiful texture.

Four ED (Extra-Low Dispersion) glass elements and a single Super ED glass element minimize chromatic aberration and prevent color bleeding, not only in the main focus area, but also in surrounding out-of-focus areas.

PENTAX Original HD Coating is a high-grade, multi-layer coating that reduces average reflectance in the visible spectrum to less than 50 percent, effectively minimizing ghosting and flare in demanding lighting and backlighting conditions.

This lens incorporates an electromagnetic diaphragm mechanism to ensure high-precision exposure control when used in combination with compatible digital SLR cameras. Ensures smooth and worry-free video shooting in locations prone to large changes in brightness, such as a stage with rapidly changing lighting conditions or a forest with filtered sunbeams.

• The 21mm ultra-wide-angle lens is designed for full-frame Pentax K-mount cameras; however, it can also be used with APS-C models where it will provide a 31.5mm equivalent focal length.
• SP (Super Protect) coating keeps the front surface of the lens free of dust or smudges.
• Built-in motor to drive the AF mechanism for smooth and quiet autofocus operation.
• The eight-blade circular diaphragm produces beautiful beams with pointed light sources and creates a beautiful natural bokeh effect at wide and larger apertures.
• QFS/A (Quick Shift Focus System) to instantly switch to manual focus mode without the need for focus mode shift operations, after the camera's autofocus system has captured the subject in focus.
