i was at the camera store today to return a lens i rented, and i had some issues with the IS on the lens so i just made a remark about it.

the guy was like, oh can i see your camera? so i show him (it had the mount cap on, no lens) he takes it off and puts the lens i rented on it, tests it, says it's fine and then he says, let me go check on something. then the fucker takes the lens fucking off... and leaves my camera right there out in the open with no lens on it, no cap, nothing... he walks away for like 30 seconds and comes back with another lens to try on it

what the fuck, could anything damage the sensor like this? i change my lenses but i do it super fast in like 2 seconds. this time it was left in the open for more than 30 seconds on the counter. i don't have anything to clean it
