9-blade rounded polygon bokeh
Optical Evaluation: At 50mm f/2.8 with 9 aperture blades, this lens provides a geometric entrance pupil of 17.86 mm. The depth of field spans 0.24 m around a subject at 2.0m. Out-of-focus highlights will show a distinct 9-blade rounded polygon bokeh with minimal edge fringing. With an Airy disk radius of 3.78 µm, resolving power is well clear of diffraction penalties.
