There are only a few lenses that produce a truly creamy bokeh (depending on your definition of creamy).

Which ones would you put in this category? (for various mounts) ;-)

Well, truly creamy are only those with an apodization element.

My 70-200mm f4 USM does do truly creamy (in the background).
Some lenses are (truly) creamy only at certain distances. The Canon EF 35mm f2 does not render at all smoothly at medium distance focussing, but at close up distances... it gets creamy. Way more creamy than my Nikkor 55mm f3.5 at similar distances, it is not just a more blur due to the distance thing.
I think that some lenses show strong(ish) outlines in bokeh discs at "normal" distances, and at close up distances these outlines disappear, which explains the transformation.

This Samyang does not do creamy at portrait distances.

On lenses with apodization elements... The Sony 10mm f2.8 STF does do truly creamy. The Loawa 105mm f2 STF does do truly creamy. The Canon RF 85mm f1.2 does do truly creamy. The Fuji 56mm f1.2 APD does NOT do truly creamy, not even close (perhaps it does at close ups).

The Olympus 17mm and 45mm have a feathered bokeh as well.

The Olympus 17mm and 45mm have a feathered bokeh as well.

You may add the 25 Pro as well here. Not officially "feathered", as the term was only coined with the 45, but both fore- and background OOF areas and the transition to both is very gradual and beautiful (IMO anyway ).

Kind regards, Wim
