A word of advice with these older lenses, don't let the sun get too close to the front of the lens, you will lose contrast. I've experienced this with quite a few of the 135mm lenses and I've still got a couple to test. They all experience the same thing. If you have the sun behind you then the image quality is excellent. See the image in todays post. You can get this lens for very little and there are a lot of them out there on the market.
