Summarits are no necessarily hazy. Mine is not
I have test it against 50 Summiluxes and kept the one I have.
The new 50 1.4 that is never in stock is something else again. Fabulous lens. Best 50 mm I ever had on a camera,
I don`t think much of CV lenses. Have a few, 12,15,24 in screw mount, and while ok for a screw mt body, I feel Leicas are better.
