constant aperture question (camera vs. lens)?
constant aperture question (camera vs. lens)? Hi, Friends - I'm using my friend's canon 15-35mm f/2.8 lens on a canon r6mii camera this weekend. As a novice, I'm confused as to why the lens is a constant 2.8, but on the camera itself I can stop down? Isn't the whole point that I maintain the 2.8 through the entire focal range?
