I just got a second hand Nikon D50. This is first reflex camera I ever had. I am trying to take macro of an electrical component in relatively dark room.
These are the settings on my top display:
I switched the objective mechanic switch to manual focus mode. When I press the shutter button halfway, I can still hear the camera do some motor sounds. Almost as if it was trying to focus. And once I press the shutter down completely, nothing happens.
When I press and hold the AE-L/AF-L button before attempting to take picture, it does take it.
Why does it refuse to take pictures and what does holding AE-L/AF-L button have to do with that?
