I am sure this is discussed before, but was not able to find it easily. I am in search of portrait lens in the 80-110mm focal length (actual FL). Here are some lenses that come to mind. I love the sonnar rendering of zeiss lenses and these are lenses thought to have that as well. 1. Contax C/Y 85mm f1.4 2. Contax C/Y 85mm f2.8 3. Contax G 90mm f2.8 3. Nikon 105mm f2.5 4. Olympus OM 85mm f2 Please let me know your experience or other lenses to consider. At this point, I am not considering the new Oly 75mm simple due to the clinical and lack of 3D rendering.
