PS. Once you got little more shooting with the lens, please report what you find out. Your descriptions of optical errors are always top-notch.
Well, I am not much of a lens tester. I am more interested in optical phenomena than in lens tests or comparisons, but occasionally I join the test crowds. We\'ll see.
Today I went out with a bagful of Distagons and tackled a museum wall. The framing is about the same with all lenses, but slightly more tilted as the focal length decreases because the patch of grass goes downhill towards the building. This subject is not well suited to study lateral chromatic aberration because there is not much color variation or high contrasts, but still there are clear differences between these lenses. Focus is on the arch above the door, using 10x live view at the maximum aperture. You best download the images and compare them in your favorite viewer. The image magnification is 0.003, representative of infinity performance. Don\'t look at the grass in the foreground, which is out of focus.
