INCORRECT EXPOSURE

CHALLENGE:

Your camera seems unable to properly expose your images, with underexposure or overexposure occurring repeatedly, regardless of the shooting mode selected. Depth-offield control is also unavailable.

SOLUTION:

If using a lens with an aperture ring, ensure this is set to the A position for automatic aperture control, without which exposure can only be controlled with shutter speed. Alternatively the aperture ribbon may have failed, requiring a simple repair.
