Standard-length, 52.5mm equivalent prime lens provides a similar field of view to normal vision, making it well-suited to use in everyday situations. Fast f/1.4 maximum aperture benefits working in low-light conditions and provides greater control over focus placement for shallow depth of field applications. Two high refractive index elements and one aspherical element reduce chromatic aberrations in order to produce greater sharpness and clarity. UMC coating improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images. Eight rounded aperture blades help to produce an aesthetic out-of-focus quality to benefit selective focus and shallow depth of field imagery.
