I bought the Opteka 2X Telephoto lens for my Olympus C-8080 Camedia Digital Camera so I could zoom in closer to my subject or scene.Unfortunately, I have not noticed much of, if any useful difference in the closeness of the subject or scene.And the lens attachment has one terribly annoying side effect: Whatever you zoom in on, is surrounded by a black circle and yes, it comes out in your photo creating the effect as if you had taken it through a telecope or pericope.Maybe I'm not using it right, but I have followed any instructions given, and it's just not right.Buy if you don't mind a periscope effect or just need a slight edge in aooming in closer, go ahead and buy it, it's cheaper than the T-Con which I'm starting to regret I didn't buy because it said only 1.4X zoom.Hope this helps.
