Just a very fast bokeh comparison between the 24mm f/1.4 MkII, 50mm f/1.2, 85mm f/1.2 MkI, 135mm f/2, and just for fun then 17mm f/4 TS-E. Oh and everything is wide open.
not sure if it any help for anyone but here it is anyway

24mm f/1.4



50mm f/1.2



85mm f/1.2



135mm f/2



and just for fun... kinda ugly bokeh actually...
