The UV filter, also known as a haze filter, is not only an excellent universal filter for visually improving photographs with all film types, but it can always stay on the lens for protection from dust, fingerprints, moisture, etc. and for use under extreme conditions It absorbs the short wave portion of the spectrum so under hazy conditions a clearer reproduction of the scene is possible. The loss of sharpness caused by UV rays and the bluish tones common in infinity scenes are eliminated with the colorless UV filter. An exposure correction is not required.

Heliopan filters are simply the best you can get. Rather than repeating the virtues listed in the company's advertising, I'll just say that I periodically try other brands, which are invariably less expensive, but aside from Singh-Ray specialty items, I'm just never happy with anything else when I compare it to a Heliopan. The mounts are slimmer than B+W's F-Pro mounts, and work great even on ultrawides; they are solid; they are machined perfectly; they have a nice, matte finish that is easy to grip for putting them on and taking them off; they stay put, and the glass always fits tightly. The glass itself is of such high quality that you don't have to worry that you are sacrificing anything even when you put a filter on a Leica lens. I go overboard, putting Heliopans on everything (Leica, Nikon, and even Lensbaby lenses), but even where the quality of the glass is overkill, the slim, elegant mounts make them worthwhile.
