| May 15, 2017 at 23:19 | comment | added | Taro | Thanks, Mike, Matthieu and Scott. All these comments are very helpful. So, what I'm getting is that for a lens, d approaches f as D increases, correct? If that's the case, I'll need to determine the D at which point d ≈ f. | |

| May 15, 2017 at 18:16 | comment | added | scottbb♦ | @MatthieuMoy bingo. The OP's "D = f*H/h" only holds for all distances for idealized pinhole cameras (in which case, d = f always). | |
