The Fujinon XF 56mm F1.2 R is an interchangeable camera lens announced by Fujifilm on January 6, 2014. As of 2015, it is one of the widest-aperture native mirrorless lenses.
APD variant
In September 2014, Fujifilm announced an additional variant of this lens, the Fujinon XF 56mm F1.2 R APD, which has an additional APD filter element for apodisation, with the goal of improving the appearance of out-of-focus areas, or bokeh, when the lens is used wide open. As a side effect, light transmission is reduced at the widest apertures, making f/1.2 effectively t/1.7, having progressively less light reduction until f/5.6, beyond which the APD lens has the same light gathering as the standard model without the internal filter.[1] The APD lens also cannot take advantage of phase detection autofocus on cameras with this function, relying instead on slower contrast detection autofocus.[1]
