56/1.2 APD vs 56/1.2: Defocused Bokeh
Here focus was at very close range so as to show the bokeh quality of out of focus light blobs. The point sources are irregular bullet holes in the metal siding of a barn. Some are circular, and some jagged.
The Fujifilm XF 56mm f/1.2 APD utilizes an apodization filter which is most effective from f/1.2 through f/2.8. This is why Fujifilm supplies the lens with a 3-stop ND filter to enable shooting at wide apertures even in very bright light. At f/4 and beyond, the effects are minimal, as will be seen below.
Some difficulty was encountered with the two lenses on every one of 15 or so comparisons: a shift of image center, observed when swapping lenses. The images here have been aligned by 42 pixels horizontally, and 15 pixels vertically. One of the lenses thus has its optical group rather off-center.
