The Fujifilm XF 56mm f/1.2 R APD Lens is short telephoto-length prime lens that provides a 35mm-equivalent focal length of 85mm, making it ideal for portraiture and other applications where a slightly longer-than-normal perspective and flattening appearance is desired. A fast maximum aperture of f/1.2 and APD (apodizing) filter come together to produce sharp main subjects and even smoother bokeh, giving your photographs an overall three-dimensional quality. This effect is furthered by seven rounded diaphragm blades, to produce circular out-of-focus highlights.
Optically the 56mm APD features 11 elements in 8 groups and includes one aspherical element, two extra-low dispersion elements, and three cemented elements, for a marked reduction in chromatic aberrations, distortions, and colour fringing throughout the aperture range. An HT-EBC multi-layer coating has also been applied to elements to minimise surface reflections, flare, and ghosting.
The apodization filter performs best at wider aperture values, so a 3-step ND filter is built into the lens to aid in controlling exposure. Using two separate sets of aperture values, the red series of numbers indicates the effective aperture value as it relates to depth of field. The standard white set of numbers indicates the actual f/stop number, and the difference between these two sets of numbers indicates the effectiveness of the filter.
