This morning I have one; typically I only remember a dream if I wake up part way through, so it is fragmentary.
I was sitting talking to an acquaintance; he was at his desk and I was sitting in front of the desk. I happened to notice a camera and detached lens sitting on his desk over to the side among other items. I said that's my camera isn't it, and picked it up. Yes, I was very familiar with this camera, so I started to mount the lens.
The camera had a very bulgy shape, with a big built-in grip and other bulges on the front. The lens was bayonet mount but didn't twist to lock. Instead there was an opening in the bottom below the lens mount with a chain sticking through. One grasped the chain with forefinger and thumb and the opening allowed manipulating the chain to turn a trapped collar, I guess threaded, so that it secured the lens from the inside.
But it wouldn't tighten the lens, the collar just kept turning and turning, and it was frustrating with only the chain to work with.
As I was doing this we were talking about the repair order. I must have brought the camera to him for service. But he explained that there were too many things requested on the service; he could (or was allowed) to do only 4 repair items, whereas I'd asked for more. So, not knowing which 4 to do, he'd done none.
There was no more, as my cat tickled my face with her whiskers, time to get up.
