Re: Teleconverters RF vs EF

Ok, I just checked, and a RF to EF adapter wont connect to a RF teleconverter (the part of the teleconverter that sticks out is larger diameter than the hole in the RF to EF adapter).

But, the question still remains for the big white RF lenses.  I would think that the optical design of the teleconverter would be for it to be next to the back of the lens.  With the "Big White" RF lenses, since they are essentially a EF lens with a RF to EF adapter built in, does moving the RF to EF adapter to between lens and tele affect the image quality of the RF lens with a RF tele on it?  i.e. is a EF 600F4 iii with a EF 1.4x iii optically better than a RF 600F4 with a RF 1.4x tele?  I dont know enough about lens design to know if the added space between lens and tele (on RF Big Whites) changes anything.
