Have you verified that the camera's rangefinder is properly aligned? I had a similar problem with that lens and it turned out to be the camera's rangefinder. I didn't realize this until I set the camera up on a tripod, drew an "X" target on a flat surface, and CAREFULLY focused on the target (at the mimimum focusing distance), and shot one frame at f/1.4 and another at f/11. The large depth of field at f/11 gave me a sharp "reference" image of the target, to compare to the one that I thought should be properly focused at f/1.4. I also shot two more frames at f/1.4, intentionally focusing just forward and just behind the target. I could see the difference right on the negatives with very little magnification. Of course at f/1.4 the image will look a little less defined, but it was clear to me that it was also simply out of focus. One of the images that I focused just behind the target ended up appearing in focus on the negative (matching the f/11 exposure). And by the way, that was a NEW body. Listening, Leica? :) - --Andrew
