It is the ideal choice for carry- everywhere, instantaneous wide angle or snapshot photography. The versatile angle of view produces natural images with a moderate perspective, or an expanded depth of field, making it ideal for many different types of subjects, stories, landscapes and life’s special occasions. High-grade HD coating for exceptional image rendition All lenses are treated with HD coating, a high-grade multi-layer lens coating that assures higher light transmittance and lower reflectance than conventional multi-layer coatings. As the result, they produce sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.

This diaphragm produces a natural, beautiful bokeh (out-of-focus) effect, while minimizing the streaking effect of point light sources.
