Heliopan 46mm UV Filter (704601) with Specialty Schott Glass in Floating Brass Ring

I have been looking for the best UV filter for my 20mm f1.7 lumix lens. When I have found this Heliopan expensive filter I thought it was a very good quality filter because it's high price and Germany made(also I have read Heliopan web).I was wrong. It produces LOTS OF FLARE with artifical and natural light. It doesn't have enough coating. My Marumi DHG Lens protector (13 USD) cheap filter work better than this Heliopan. I'm not US resident so thats why I can't return it.Thanks!

I was extremely disappointed by this filter. I initially thought that it was a high quality German filter. The craftsmanship of the filter is worst than any quality Japanese brands (hoya, Kenko, Nikon and etc.) which are 2x cheaper mostly. The finish of the metal bezel is rough, and the words looked like they were painted on and showed unevenness. Worst of all, this filter has the worst coating I've ever seen. Comparing the amount of refection between this one and my B+W and Sigma DG uv filters, this one looked like a mirror and reflected a LOT of light, which shows inferior coating. The price of this filter is highway robbery considering the low quality and performance it offers.

I'm happy to get this filter on my Panasonic 20mm pancake lens on my E-PL1. It really takes some of the length off the combination, even though it's only about 1mm less thick than the Tiffen I had on there, it seems to make a big difference when cramming the outfit into a laptop bag and all that. With the tiffen, I swear I could tell it was on there, with an ever-so-slight loss of light. I can take the heliopan on and off all day and can't tell the difference. Psychosomatic? Maybe. But like I said, $38 is not a big deal to spend for happiness.
