| beginner's question: focal length & diop |
| 30 Sep 13 12:37:26 |
From: invalid@nospam.com Apologies if this is basic. I am trying to work out the diopter strength of two lenses. One has a focal length of 18.5cm and the other 4cm. Is the diopter strength 5.4 and 25 respectively? Thank you for any help. --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
