I compared the 28mm with the Minolta AF 28mm f/2.8, which has an identical spec (both with apertures f/2.8 to f/22). I took a series of photographs of a two-page spread of a newspaper to check the resolution. At f/2.8 the Elmarit shows excellent sharpness, across the frame - better than the 50mm Summicron at f/2. Compared to the Minolta, it is streets ahead - the Minolta at any aperture cannot match the sharpness of the Elamrit at f/2.8 right in the corners of the frame!! Stopping down hardly improves the performance of this magnificent lens. At f/11 to f/22 diffraction comes in slighly, but is hardly noticeable. I did the same test with the 50 and 100 lenses, which were also far superior to their Minolta equivalents, but I would stick my neck out and say the 28 was even better than the famous 100 APO macro! In the real world, the photos I have got with the 28 are superb - I recently took some pictures with very strong sunlight almost directly in front of the lens, and there was no flare. By the way, the lens hood is removable as I used a jewellers screwdriver to take it off, as I use Cokin filters and the hood gets in the way. I hope this helps - unfortunately I didn't have the old 28mm to compare, but I would imagine the newer lens shows better performance at larger apertures, which showed such a good result in my tests.
