The olympus M.Zuiko ED 25mm f/1.2 PRO is a 50mm equivalent focal length lens
designed for Micro Four Thirds mirrorless cameras. Its unique 19 elements, 14
groups construction incorporates extra-low dispersion, aspherical, and high
refractive index elements to significantly reduce both spherical and chromatic
aberrations for notable image clarity, sharpness, and colour accuracy. The lens
is also characterised by a bright f/1.2 maximum aperture, which benefits
working in low-light conditions and also affords extensive control over depth
of field. A nine-blade aperture is featured as well, to achieve a smooth bokeh
quality when working with shallow depth of field techniques.
