[QUOTE="Fred Kingston_RIP, post: 728060, member: 10742"] Big difference between the Kenko telconverter and the TC-200 he's using. The Kenko has elec. contacts and the TC-200 does not. The TC-200 can be made out of a block of wood and would retain the same electrical characteristics. ;) Has nothing to do with the camera model. It's all in that P series lens requirements. There's a focus ring on the P series. It is not a manual clutch connection, it is an electric sensor connection... No elec. from the camera body and that lens will not manually focus. Here's an exercise to try if you have a P lens. Put it on your camera and focus. Pull the battery out of the camera and turn the focus ring. I bet 2 internet bucks it won't manually focus. [/QUOTE]
