Lens accessories: adapters, rings, polarizers
The small parts without which optics will not meet the camera. Adapter rings join different mounts — M42, M58, M72 to C-mount and F-mount. C-C extension rings shorten the minimum object distance when a part has to be imaged larger. Linear polarizers suppress specular glare — primarily from glass, film and plastic; on metal they only help in a cross-polarized lighting setup.

How to choose
An adapter is chosen by the pair of mounts and by thickness: it counts towards the flange distance, and an extra millimetre shifts focus. A polarizer is chosen by the lens front thread (M27, M30.5, M35.5, M37, M40.5, M43) — listed in the lens specification as filter thread.
