Having read the comments on the degrading effects of filters, frankly I just didn't believe it, so I decided to carry out my own tests. I used a canon 100/400 mm lens at f5.6 and 1/320 s on a tripod and using an electronic release. Light did not permit a faster shutter speed even at 800 ISO. The filter was a Hoya HMC Super Pro 1 and it was clean!. The shooting distance was 10 m. The results have absolutely astonished me. From now on it's good-by filters. Results are maximum quality jpegs straight from the camera, no post processing except crop.
