Here is another question I have. With the old 35 MM film cameras, you had to set the ASA of the film on the camera. How is it with these digitals? Is it something that is just obsolete, and no longer a concern? How does the camera know the F-Stop in relationship to the shutter speed? Bear with me here, it's been 35 years since I popped the shutter on a 35 MM camera. As they say, I know just enough to be dangerous.
