I know that placing anything in between the lens and subject will degrade the image to some degree. That's why I generally don't use any filters.

But at times I do wedge my lens through thick brush or shoot in misty/dusty environments so I would like to get some protection some times.

Question 1: Hoya (and I'm sure other brands) has at least 3 grades of filters - cheap, modest, and over-the-top. Has anyone tried them out to see if there is a big difference? I see filters coined "digital" filters for the most expensive stuff.

Question 2: A premium "film" filter cannot be considered a premium "digital" filter?


I'm looking at purchasing a few "digital protection" filters (not UV) for occassional use. I would appreciate any feedback as to whether the image is degraded appreciably.

Thanks a bunch!
