However sometimes when you stop a lens down to that degree you may get distortion so I could also be wrong. It also depends on what kind of focused distance you are talking about too. With the focused distance being say 1 foot your DOF with F16 is going to be from 11" - 13.5" or so. Focused distance being say 15 feet then the DOF is going to be from about 4 feet to infinity. These numbers are just approximations and do not represent the true values of the lens.Back in the early days when film was the only option people had many 35mm lenses of all lengths had a different color for F8. The reason they did this was because many folks would set it at F8 and infinity and then forget it because the DOF would be such that after however many few feet everything would be in perfect focus. So that eliminated the issue of focusing the lens for most pictures, it eliminated the need to set your stop, and so all you had to do was meter the situation real fast and set the shutter speed. Just as now back then lots of people turned to the old 110 Kodak cameras and what not because 35mm was just to damn complicated for them. In reality it is not complicated at all once you understand a few things about it. And this is why they invented auto everything cameras and eventually digital P&S rigs...people are just lazy they want everything done for them and done instantly which is OK I guess. Not me I would almost try to rub two sticks together to start a fire instead of using matches when it comes to camera settings. I'm just hard headed that way but because of that I can pick up almost any camera anywhere and use it competently. It took me all of about 2 minutes to know my D5000 when I first got it.</blockquote>
