Can anyone interpret the language in the patent application? For
example, what are:
"annular packing made of a resilient material"
"packing-compatible camera body" and "packing-incompatible camera body"
Annular packing made of a resilient material == rubber 'O'-ring.
"Annular" means it's a circle; a ring ... it's shaped like a donut.
The way I read the description, the patent application is for a lens
mount that has two concentric mounting bayonets, an inner and an outer,
with some kind of rubber 'O'-ring in between.
One type of camera would fit the inner bayonet and another camera would
fit the outer bayonet.
When the lens is mounted on the camera that takes the inner bayonet, the
rubber donut in between the two bayonets keeps the outer one from
scratching the front of the camera.
It'd be like a lens that could mount to either a K-mount OR to a
P645/P67 mount without needing special adapters.
