I'm using a Nikon DSLR. I noticed that the Fxx/x thingy which i think is the aperture, becomes F --/- . There are usually digits after the F to show the amount of light but it becomes blank ( - ) sometimes and that is when my camera won't capture pictures. I can take many pictures at a time and the next second, I can't ( When the F becomes blank ) This happens at any light intensity.
