I really like the Olympus half frame lenses, which I've tested to be as good or better than most LTM rangefinder lenses, including Leica. I had a 40/1.4 once that I sold because of haze, but saw this other one at a sale, with a 100mm 3.5 too. It was one of those "grab what you want and pay" sales, I paid very little, and took it to my car. Later, I looked in the case, and was very happy to find a third lens, the 38mm Pancake! Shooting them all, they are all clear as a bell.
