I am not good at reading MTFs but after Wah's comment on the 85/4 I took a look at the various MTFs of ZM 85/2 Sonnar, 85/1.4 C/Y Planar and 85/2.8 C/Y Sonnar.
To me the MTF of the ZM 85/2 at f4 seems to be the best amoung all (correct me if I am wrong). What puzzle me if I am correct is how come a range finder 85mm can be superior to SLR version as design wise I believe the SLR version should not have the mirror restriction in design consideration.
Maybe Zeiss just need to make the ZM version better so that they can justify to make in Germany at selling at the price?
Actually I was always thinking if ZM Sonnar 85/2 can be re-mounted into ZF Sonnar 85/2! As the rear element is quite far away from the film plane which similar to the case of Sonnar 90/2.8 of CONTAX G.........
Anyway another reason for its higher price is due to the floating element design, which should be rather costly to manufacuture especially with the rangefinder coupling mechanism.
The only other mid-tele Zeiss lens with floating element design should be Planar 85/1.2!
