Hello, I have a digital Olympus SP-500 UZ and I am going to be using it for portrait photography. I would like to capture a sharp image of the subject, with the background out of focus. I ordered the Conversion lens adapter CLA-4 to be able to attach a lens for this. I have 2 questions for you- 1- I saw that the only lens Olympus carries is "Telephoto lens TCON-17." I know this is for magnifiying things from a far. Would this product be able to capture a close subject sharply with a blurred background? If not, does the Conversion lens adapter CLA-4 attach to any other lenses besides this one? Preferably a 200mm lens. Do other brand lenses attach to this? Any help would be greatly appreciated.
