I don't know where they found that results but having B+W , Heliopan and Singh ray filters I find Heliopan being the best
Thanks for the recommendations. I went ahead and ordered B+W filters yesterday.
I'd like to continue by saying that we are in one of the most expensive fields in the industry. Technology drives the market. Computers become obsolete in five years. Cameras and lenses make incredible advances. I end up turning all of my profit back into gear.
A friend of mine just bought a Canon 7D. He said that it took him him weeks to learn all the settings. Each lenses can be attached to the body, and calibrated for focus (via a menu). I don't know about you, but I just want to shoot and produce good art. i get a little tired of having to learn new technology.
