The Sonnar 180mm is one of my favorite telephoto lens. There are many version of this lens since its introduction
back in 1936 Olympics.
I got the 180mm Zebra single coated version. They're actually better build than the MC version.
What I like about this lens its color and contrast. Not over contrast like many Japanese lens which filtered
out many colors. No vignette issue at wide open. Great for portrait as well.
