Sorry if it's been asked before, but latley I have read about this term and couldn't figure out exactly what it meant based on the context.

Long, Long ago, there was 2 ways to fit a lens to a camera. Companies like Pentax and Zenith used to use them. One was a bayonet mount and the other a screw fitting. Think of it like a light bulb, one screws in and the other is similar to a bayonet. Most cameras now use the bayonet fitting, i.e, insert-twist-click, funnily enough, just like the fitting of a bayonet to a gun. This applies to most places where you see "Bayonet". Hope this answers your question.



Regards.

It usually refers to the way a lens mounts to a camera. Rather than a screw thread (like a filter has), on the lens there are three tabs that allow it to fit into three cut out sections of a ring, and once in you turn the lens for those sections to interconnect and then either by friction or with a locking pin the lens is tightened into position.

As you didn't provide the context yourself, can't be sure if that's exactly what you're talking about, but that's what's usually meant. "Bayonet mount" actually comes from the term of mounting a "bayonet" to a musket, which is a type of gun used in the Civil War:

Thanks. I knew it was how a lens mounts, but I didn't understand the twist and click part. Now I get it.
