Lens Features: Smooth Trans Focus, Sharp in-focus image and creamy bokeh.

It is intended to smooth the transition between the plane of focus and out-of-focus areas in the image so as to achieve the effect of sharpness in-focus and creamy bokeh and eliminate the linear bokeh.

Optical Properties: A piece of apodization element is set near the aperture diaphragm with low reflective multi-layer coating.

Every lens element adopts the multi-layer of low reflectance coating which completely eliminates ghosting and flare. A piece of apodization element has been inserted next to the aperture diaphragm to converge the light towards the center of the lens and reduce the amount of light gradually towards the periphery. This STF design produces images with crystal sharpness at the plane f focus and at the same time, gradually melting away to form a soft, natural and beautifully diffused out of the focus rendition. And for imaging with more high-quality, three pieces of low dispersion element and high refractive element are used to achieve outstanding image while keeps lens compact all the time.

Structure Design: It is completely made of metal. 

The lens is solid built with metal to ensure high assembly precision and durability.
