Extend the capabilities of your digital camera with the Olympus TCON-17F Telephoto Converter lens. This telephoto lens will increase the magnification of your subject by 1.7x when your camera lens is set to the telephoto position. This will help you bring in the subject when you can't get closer, such as shooting sports or concerts. This lens is compatible with the SP-310, SP-320 and SP-350 cameras, which require the CLA-9 lens adapter tube.
