Fujifilm's APD variant of the 56mm f/1.2 — adds apodisation filter for ultra-smooth bokeh rendering.
The Fujifilm XF 56mm f/1.2 R APD was released in 2014 as the apodization-filter variant of the XF 56mm f/1.2, adding an APD (apodization) element that gradually attenuates peripheral light for smoother out-of-focus transition. Eleven elements in 8 groups. Seven rounded aperture blades. 62mm filter thread. At 405g. 0.70m MFD. The APD element physically disables phase-detection autofocus.
The optical design uses 11 elements in 8 groups (1 aspherical + 2 ED + 1 APD filter element). Seven rounded aperture blades. The 62mm filter thread. At 405g the lens is moderate. Minimum focus distance of 0.70m. The APD element blocks the peripheral light paths that phase-detect AF relies on — PDAF is disabled; AF falls back to contrast-detect only (slower and less reliable for moving subjects). f/1.2 maximum aperture.
The APD element trades AF performance for smoother bokeh rendering: the graduated neutral-density effect of the APD filter softens the transition between in-focus and out-of-focus areas, reducing the 'busy' bokeh that can appear at f/1.2 in standard designs. The practical consequence is that the APD version is suited to static portraiture rather than tracking subjects — the contrast-detect-only AF is too slow for action.
On the used market the Fujifilm XF 56mm f/1.2 R APD is available at a premium over the standard non-APD version. Condition checks: contrast-detect AF response (expect slower than non-APD), 62mm front element for marks. APD = no phase-detect AF. Compatible with all Fujifilm X-mount APS-C bodies.
