I just recently got a 49mm Lensmate and UV filter that I plan to leave on my G2. Today I received a Tele-Converter, also 49mm. Should I remove the UV filter when I use the Tele-Converter or can I simply add it to the UV filter without loss of image quality. I also have 49mm close-up lens. Can I use these behind the Tele-Converter for macro shots?
