I did!
I had the M 2/85 and sold it - the Samy 1,4/85 staying (beside the Pentax M 2,8/100).
The Pentax' advantage is being small and lightweight.
Yes: the old K 1.8/85 is quite a tad better in sharpness and contrast.... but at least 50% more expensive....
Another Option - if 2.8 will be 'fast' enough (I think it's all about small DOF and blurring Background - is for me the big&heavy 2.8/70-200 (Tamron).
Being an AF-lens I just don't care about wrong Manual focussing.
Same with my Sigma 1,4/50 HSM: very good for Portraits.
Besides I use Tamron 90 mm macro lens:
the old 2.5 makes a lovely background softness wide opened but good center sharpness (at 2.5 !) - stopped down it becomes an Overall very sharp lens.
The new 2.8/90 macro is very sharp even wide opened....
