You can bet the farm that they are related. The larger the opening of the lens (f/2.8) the less depth of field and the smaller the opening (f/16) the more depth of field. The closer you are to the subject, the less depth and the farther away the more depth. The wider angle lenses the more depth of field. Telephoto lens, the less depth of field. As said before, read and shoot, practice, practice, practice, learn, learn, learn. Nothing like the school of hard knox.
Correct but as relates to focal length having to do with depth of field .It doesn't and you can prove it .Aperture of lens plus subject to film/sensor distance are the only controlling factors .
I am now braced for e's declaring I'm a know nothing nut .
