In informal testing the background bokeh of the Hasselblad XCD 90 mm f/2.5 V lens looked very smooth. I no longer have access to the artificial star I usually use for this kind of testing, but I improvised with a NAS box with disk activity lights. With the lens wide open and ISO set to 64, I made a series of exposures with the lens focus distance set from minimum focus distance to infinity.
The OOF bokeh balls are very smooth here.
And they stay smooth all the way to in-focus.
Mildly OOF, the balls are still smooth.
But as the focus distance moves well behind the lights, they begin to acquire more energy towards the periphery of the circle of confusion.
Not bad, though. Actually, better than not bad. Quite nice. And I don’t see any onion ring bokeh.
I think most anybody would be satisfied with this performance. Having the background out of focus is much more common than having the foreground OOF.
