The key features

• High quality finish and excellent optical performance
• High Definition Coating
• Round shaped diaphragm
• AL Aspherical element

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.

* HD stands for High Definition, and signifies the lens's capacity to reproduce images that excel in transparency, definition, resolution and rendition.

Round-shaped diaphragm for beautiful out-of-focus rendition
All lenses feature a completely round-shaped diaphragm to optimize the performance of their distinctive optics. This diaphragm produces a natural, beautiful bokeh (out-of-focus) effect, while minimizing the streaking effect of point light sources.

Premium quality of the Limited Lens-series
While inheriting the design concept of the Limited Lens series, these lenses were designed by combining a series of mechanical and numerical evaluations with human assessment of test-shooting samples to assure the ultimate in image reproduction. Their optical design has been optimized for digital photography to deliver sharp, clear images with outstanding contrast, even at the maximum aperture. In addition, their lens barrel, hood and cap are all made of a high-grade aluminum material, hand-machined for perfect proportions and beautiful texture.
