I have a number of Canon, Nikon and CZJ 85mm lenses in LTM, including the Canon 85/1.5, 85/1.8, 85/1.9 and 85/2, Nikon 85/2 and CZJ 85/2. In general the 85/1.5 is just so heavy that it does not balance well on any camera body. A unique look wide open, but prone to flare and low contrast. The performance improves a lot, i.e., the image looks a lot more "normal", as you stop it down. By f2.8 it performs about as well as the lenses on my list. I have a preference for the rendering of the Sonnar design, so I generally go for the CZJ or Nikon, although it is a toss-up with the Canon 85/1.8 which is just a gorgeous lens, and a Gauss design, I think
