<b>Hybrid aspherical lenses(H-ASP)</b>
Hybride aspherical lenses provide excellent image and contrast even through maximum aperture in center and edge of frame.
<b>High Refractive, extra low dispersion(HR ED)</b>
High refractive elements and low dispersion lenses reduce chromatic aberation effectively to get excellent image quaility.
<b>Ultra multi coating(UMC)</b>
We apply the UMC(ultra multi coating) of our own technology to reduce flare and ghost as much as possible and get clear and fresh color image.
<b>Glass aspherical lenses(AS)</b>
The adaption glass aspherical lenses reproduce aberration to get high quality image in center and edge of frame and excellent contrast.

The internal focusing controls focusing inside of barrels so that is so free from contamination of dust.
<b>Circular aperture with 6 blades</b>
6 aperture blades create almost a full circle when closed and express ray beautifully as starlight.
