I noticed a interesting video on youtube claiming that visico UV filters are scam. Here is the link to this video: [ame]http://www.youtube.com/watch?v=U5DPVme8Ak8[/ame] Can anyone say is that true? I already bought myself a visico UV filter. I am on low budget, and i though about buying more visico filters like ND and polarizing filters. They are cheaper than hoya for example. Has anyone used visico filters? Can anyone tell is there huge difference compared to hoya or other well known brands?
