Re: Teleconverters RF vs EF

I'd honestly expect some difference between the performance of the EF and RF extenders on the EF/RF versions of the 600mm, just due to the fact that they're intended for lenses designed for different flange distances. I wonder if the assumption for RF versions of the big white lenses was that the image as projected by the rear element is close enough to parallel to the sensor that the position of the teleconverter wouldn't make as much of a difference (particularly since the RF teleconverters seem to be optically better than the EF versions).

I doubt there are too many people with both the EF and RF versions of the 600mm sitting around that could do a proper controlled comparison on the same body though :-D.
