Well, in spite of the observation of JBAPhoto, I am amused by all of the descriptions of the sounds our equipment makes. For a long time, I have tried to describe the sound of my 1964 Minolta SR-1b as a "FLACK--Vszzzt--FLOCK!!"
Then there is the Koni-Omega Rapid M. The leaf shutter in the lens is quite predictable and discrete, but then there is the sound it makes when you pull out the plunger on the magazine and push it back in to advance the film to the next frame and cock the shutter. It can be a bit disconcerting to anyone in law enforcement or the military. You will get the idea if I simply say that it sounds very much like a .45 ACP round as the slide is pulled back and then it goes into battery.
