i have a D40 and been taking pictures for over a year. never had problems....all of a sudden i get a message on the camera that the "subject is too dark" and the camera will not take the pic. when i switch to manual focus the camera will take the pic. when i look through the viewfinder i see a little black flashing dot on the bottom left hand side. i did not intentionally reset any settings, etc....would really appreciate any help. THANKS!!

Welcome to Nikonians! What exposure mode are you using? Did you recently change the ISO from Auto to a specific ISO setting? When the subject is too dark the Lo message appears in the viewfinder. The causes is the ambient light level is beyond the range of your current settings (Shutter Speed, Aperture (f/#), and ISO) to provide a correct exposure. To correct the problem: • Choose higher ISO sensitivity. • Decrease the shutter speed. • Choose larger aperture (smaller f/-number). The black dot in the lower left corner of the viewfinder display is the in focus indicator. Good Luck and Enjoy your Nikons!
