Canon Patent Application: Canon RF 24-70 F4L

One of my biggest waits for the RF mount is the F4.0 trinity.  This lens, the 24-70mm isn't as important, however it atypically has better optical performance than the bigger zoom ratio 24-105mm.

This patent application details multiple different optical designs, however, they all are quite similar.  Given the backfocus distance and the image height, these designs are most certainly for the RF mount.
