Northlight Images has uncovered a patent for an additional EF to RF adapter, this one would add “soft focus” capability to all EF lenses on EOS R camera bodies.

The USPTO patent shows the adapter working with all sorts of EF lenses, such as an EF 24mm f/1.4L II, EF 35mm f/1.4L II and the 135mm f/2L.

According to Northlight, “the specs point towards full frame sensors and backfocus distances which could fit with having the soft focus element inside an EF->RF adapter”

The soft focus elements are shown in red in the image below.
