Hi, i am on vacation in Zanzibar in Africa and have encountered a problem with my D40. Every time i take a photo, in any mode the result is way too dark, even on long exposures in bright daylight. I then get an error message come up telling me to press the shetter release again. It is hot here - 32 centigrade and up. Have i cooked something inside it? All advice appreciated.
Welcome to Nikonians! Sorry to hear of your problem. First check to make sure that you didn't inadvertently dial in positive exposure compensation. Make sure that the lens is fully seated and locked in the camera.
If none of the above work, try resetting the camera. If a reset doesn't work, the camera will require service Good Luck and Enjoy your Nikons!
I've occasionally had an issue with a single black picture for no apparent reason on my D40 but it never was a repeatable problem and I never had the error message telling me to press the shutter again. I don't think the heat is the issue unless you've had the camera sitting in the direct sunlight. In Arizona, I've never had an issue with high heat and I've shot in 45+ weather many times. I'd try the reset and make sure the lens is seated properly or try a different lens to see if the problem is in the camera or if it follows the lens.
Checked different lenses and that they are fitted correctly. Checked for extra exposure added in. It seems to have semi corrected itself after 2 days in an air conditioned room. No error messages now but still having to use a much slower shutter speed than i normally would to get good results.
We have 32C and over temperatures every day during Summer so I am sure it isn't that. However I am wondering if your camera is possibly being affected by high humidity or other moisture.
This is exacerbated by moving the camera out of air conditioned space into high humidity outdoors. Placing the colder camera into a plastic bag while its temperature equalises with the warm outdoors is a way to avoid condensation in or on the camera.
