...................................................Now negative review about another shop in Wan Chai Computer City, Di Gi Fi. I was already paying for Joby Gorillapod tripod and the guy started critisizing my UV filter as not a good fit for my lens. I was in rush, but was ok to get a good filter. Finally he sold me Matze HDMC UV filter 77mm for 750 HKD which is almost $100 saying many times that it's very high end made in Germany. I got it and left. Later I tried to find this manufacturer online to understand how much more I had paid and couldn't find anything about this manufacturer except its low quality web site and mentions of the brand on Alibaba.com which is Chinese ecommerce platform. Ok, Di Gi Fi sold me $100 noname (I'm sure made in China) UV filter vowing it's German made high end.
Be careful buying electronics in Hong Kong.
