Circular Polarizer
Neutral Density 3, 5, and 7 f/stops (8X, 32X, 128X) (for outdoor videography, primarily)
UV (for high altitude work > 5000 feet)
Clear Glass (lens protection in harsh environments such as beach, welding, cooking, industrial processes)
I also have adapter rings to mount my 58mm filters on the 46mm filter ring of my macro lens. No point in owning two sets of filters.
Now that's when a clear glass filter makes sense. Although I don't use one for the beach, I sure would use one for the other three and anything else similar to those three. I know there are other UHHs that say a UV filter is not needed, but I live just south of the mile high city of Denver. Right now I only have a 55mm UV filter that I use on my lenses adapted for my E-M1mrII, but eventually I will purchase a 67mm and a 72mm UV filters. I know you are absolutely right that it is useful if not absolutely needed to improve one's images above 5000'.
