A fast prime, Oshiro's 35mm f/2 is a manual focus lens designed for full-frame and APS-C-sized DSLR cameras. Oshiro's 35mm prime offers the utmost in optical construction, including ultra-low dispersion lens elements and moisture and dustproof seal on the all-metal mount and barrel. Low dispersion glass offers superior sharpness and color correction by minimizing chromatic aberration. The lens is built with 7 elements in 5 groups with Oshiro's patented optical structure to provide image clarity and color. The f/2 maximum aperture complements working in difficult lighting and also affords greater control over depth of field for selective focus applications. Ultra nano crystal multi-coating eliminates lens element reflections and reduces ghost and flare.

When changing your aperture to defocus the background, the light sources appear blurred. This 'bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. Overcome this problem through a unique design that keeps the aperture almost circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.
