My nikon d40 camera barely
ok, lets try a few things...First, make sure the knobs, buttons, settings, etc have not moved from the drop or put them back where they belong if they did move. I would suggest doing a "Green button"
reset. Turn on your camera, press and hold the two buttons that have the "green" dot next to them, release them after you see the display flash( a few seconds). this resets the camera to the factory defaults on most adjustments, enough to get it working correctly if nothing is actually broken. Once you have done that, make sure the lens is properly mounted and locked in position. check the lens to see if you can focus and zoom it by hand, this will tell you if the lens is "basically" ok. we need to see if the aperture is closing down when the picture is taken. to do this, point the camera toward you so you can see inside the front end of the lens. you should be viewing the camera like it is in the picture in the top of this post, looking at the front. watch closely inside the lens and take a picture of yourself(without flash!!). you should have seen the aperture close down and then open back up. If you saw this then the camera is working the aperture correctly. if all that is working we need to check the speed and fstop settings of the camera. a quick way to do this is as follows. I'm assuming you know how to set your camera on Manual. Set the iso at 200, go outside, on a sunny day and take a meter reading off the grass in the lawn. the meter should read fairly close to 1/200 (1/250)with your aperture set at f16. If you get this reading then your meter is working ok. next set your camera on manual, and adjust the shutter speeds from slow to fast. take a picture at slow and see if the shutter opens and closes slowly, then take a shot at fast speed to see if the speed of the shutter is "following" your commands, we are looking to see that there is a noticeable difference between "real Slow" and Real fast". if so, now we know that the shutter is working properly. if any of these don't seem right you will need to dig deeper to find the problem or get it serviced. Hopefully the lens bumped out of position when it fell, that would be the easiest to fix, but, that is all i can think of for now. Good luck, Worm1855.
