Why - because I do not have to worry about focusing. How's that? Because most old glass has a depth of field (DOF) scale on the lens barrel. So, how do you focus? I don't.
I set the desired aperture, in my example, f16. I then set the f16 mark of the DOF scale @ infinity & shoot. The other end of the DOF scale shows the minimum distance that will be in focus, in this case a bit more than 3' or about 1M.
That is how this shot was made:
Note how the rivets on the leg of the near tower are in acceptable focus as well as the water tower at infinity.
This concludes today's lesson.
