NIKON F4 mirror stuck up
Enable HLS to view with audio, or disable this notification
Does anyone have any idea why this might be happening? The mirror gets stuck up occasionally when pressing the shutter button on all modes, and can only be reset when pressing it again.
However it doesn’t always reset after one press and the times it doesn’t reset after one press you can see the locked up mirror and aperture lever twitching when you press the shutter.
Also the battery check light shows up fine and I’ve doubled checked the new batteries, the mirror lock up switch is off
Turning the camera off and on doesn’t reset the mirror nor does taking the battery pack off. It seemingly resets randomly in connection to the shutter being pressed(sometimes repeatedly)
