Patent Publication No. 2011-107255
2011.6.2 Published
2009.11.13 filing date
Conventional mount converter
Adjust the flange back only
Not consider the difference of the image circle, causing unwanted ghost light
Canon patent
Aperture converter having an adjusting means
Aperture and manual operation of locks available
And electric drive aperture, the lens can be controlled by information
With a means of communication

This looks to be a patent related to some kind of mirrorless camera system based on the interpretation from [EG] . We've seen the mount adaptor before, this seems to be related to it.
