am a firm believer that the real test of lenses is to take photographs of the subjects that you love. If you are happy with the photos, that is all you need to know about a lens. Taking photographs of test charts has never appealed to me. Life is too short. However, after taking a lot of real world photos with this lens, I began to wonder just how it compared to my other lenses. I had hoped it would be a lot better than the 75-300 IS and maybe nearly as good as the 100-400 IS but the photos didn't always look like that. Bob Atkins put out an appeal on photo.net for anyone who could do a comparison test. I had the lenses. I had the time, so why not.
