I see we have had some more high quality adapters released for users of MicroFourThirds.
With mirrorless being so flexible its led to a number of discussions on the internet and myself and other shooters about people not longer being tied to a lens mount.
Medium format and large format users have long appreciated the difference that sensor (film) size makes to an image and how different lens seem to draw an image differently.
Many Leica M shooters collect old glass for the unique look some glass gives and now with mirrorless bodies we seem to have reached the point where we can pick whatever lens we want.
