I have the filter now since about 3Monaten and I'm thrilled. I use the filter on my Canon EOS 600D EF 50mm f1.8 II on. The 600D I use a lot of the films and the filter allows me that I despite blazing sunshine can open wide the diaphragm and that brings me the desired film look. With strong darkening minimal blueness can be seen, but with the right white balance is not a problem. The value for money is just great. 5 * 5 *
