Re: Canon 2xTC with T-ring

For lenses without contacts you have to isolate the pins of the EF 2x from the body.  I don't want to gum up the pins so I simply put a little strip of paper into the camera mount and attach the teleconverter.

For manual lenses you are not trying to maintain aperture electronics so you can simply cover all the pins.
