I bought lots of cameras and lenses from them. They always had decent prices, knowledgeable salespeople, and good service. I believe they were also an outlet for refurbished Olympus goods too. It really was a great place to do business.
Cameta was a pretty small store, with a HUGE ebay presence.
Test shot I took inside the Cameta store with an Olympus 9-18mm lens in 2009. I ended up buying that lens. It was one of my favorite lenses , until I bought an Olympus 11-22mm lens, which has to be one of the very best lenses I have ever owned.
And while it is true that they did most of their business through their ebay store, I noticed their ebay store is ALSO closed. So you can forget the theory that they simply closed their store to focus on their more lucrative ebay business.
So perhaps the owner decided to retire, or had to close down for other personal reasons? The last time I visited their ebay store they had over 740,000 feedback comments with a 99.2% positive rating. That means they probably shipped over 1 million items from their online store!
