Sure, there is a slight color difference. That's to be expected from two different brands of filters with perhaps different coloration, using different glass, and with you using your eye to determine the deepest blue. Better? Neither is better ... just slightly different.
What do you mean by not being able to see the difference. You just noted the difference in color. What other differences would you expect to see between two filters? Here's a thought: go shoot a variety of pics in different circumstances, with different lenses, and different film, and then compare all the shots with both filters ... you should then be able to determine which is the best filter for your needs and style and film etc. I believe graywolf said that there's far too much time spent on technical minutia here. Both the Hoya and the B+W are good filters ... neither is going to improve your photography, and neither will take anything away from it. IMO, you're going through some unneeded mental gymnastics. Why should you care what someone else has to say about which polarizing filter THEY prefer. You're the final arbiter on what you like and what works for you. shel Alan Chan wrote: > This has nothing to do with Pentax, but I reckon there are some experts here > might be able to tell the differences.
