Steve Huff: "First things first! This lens will not compete with uber modern day sharp as a tac “perfection” lenses. It will not compete in sharpness with a modern day Leica Summicron ASPH."
The "vintage" in appearance only Ultron does indeed compete with the Leica Summicron ASPH directly, and more than holds its own. I'd say its actually the sharper lens... sacrilege for a lens that's a quarter of the price of the Summicron
