I now have converted all of these Canon extenders to be a FD to EF adapters. This will allow me at long last to use all my Canon FD lenses on my EOS camera as they where meant to be used. With no inferior optics that other adapters have, I now can have Canon quality images

Why is this the wrong thread as I am talking about a FD to EOS adapter as per thread title.

I have converted a Canon 1.4x-A as well as the 2x-A and B to EOS. The 1.4x fits full frame camera but the 2x will only fit APS-C cameras and retained the lens elements without modifications.

The one I have made so far is 2x-B for cropped sensor`only, the one for FF will be 1.4x-A. There is not any mirrorless camera that can match the top of the line EOS cameras.

There is another choice now. I have just finished my first conversion of a Canon 2x-B extender to fit a Canon EOS body with a APS-C sensor (with infinite focus) I will be doing the same for both the Canon 2x-A extender also for APS-C sensor and the Canon 1.4x-A extender but this will fit all EOS bodies including full frame.
