>>3617938>>3617967NX-M mount(6.95mm FFD) and Q-mount(9.2mm FFD) with their ultra short FFDs and are pretty good for adapting other lenses to them. I think the NX-M mount needs the NX- mount adapter then can adapt to a dozen other mounts. Q-mount has maybe 2 dozen different mount adapters for it I think.
Too bad about the 1" and 1.17" sensor sizes though. lol
