Well, I have to admit to being stunned at the results of my most recent lens test. I just picked up a beautiful copy of the Olympus E.Zuiko 135mm F/2.8 Auto-T and set up a tripod test with my cheap-o 45-200mm that I picked up for $199 on Amazon. I went into the test with an expectation that the beautiful older lens would really show well against the newer lens. I couldn't have been more wrong. I ran through all of the aperture settings with both lens and had the same custom white point set on the camera (another big surprise was the results of the color renditions of each lens. I posted the comparison that presented me the greatest surprise, the cheap-o zoom shot wide open at 135mm (or as near as I could achieve (actually registered as 144mm when matching the fields of view against the other lens). The E.Zuiko was shot at f/5.6. Not only is the "kit" lens sharper across the frame, the contrast is better and the color rendition is far more accurate. I not only have a much greater appreciation of the potential of the 45-200mm lens, I now have no real reason to keep the 135mm except to shoot in low light handheld, where it really doesn't excel anyway. I wasn't sure if there were others who might appreciate the test but I can honestly say that it really increases my enthusiasm for a lens I didn't really give much credit! The first shot is from the E.Zuiko and the second is from the 45-200mm for both the full frame shots and the 100% crops. Pretty surprising to me. Way to go Panasonic!
