Hey fordmondeo: I test drove the 85 1.4 and loved it, but the price is a little high now. Someone turned me on to the 100 2.8 and I am looking at that one even though I have the 135 f2. The used 85 1.2 II are a little cheaper than the 1.4, so is there that big of a difference in your opinion and experience between the 2? I know the DOF is razor thin on the 1.2, and we have all heard horror stories of getting the thing to focus, and if the subject moved when you took the shot it was not sharp.
My 135 f2, to my eye, produces a more pleasing background blur than the 85 1.4.
The 85 1.2 mk2 also adds a little more drama to shots but is tricky to focus in a repeatable manner on anything but static subjects.
What the 135 and 851.2 both lack is, weather sealing and image stabilization and, as I use my stuff outside and hand held, the 85 1.4 makes perfect sense.
I cannot imagine any outdoor situation where a 50mm would be better than an 85mm stabilized optic.
