Marc said: I have just received a used Nikkor F 24mm f/2 in excellent condition. I haven't had time to take any photos yet, but looking at it, I noticed a red point within the DOF scale. Between the orange (f8) and green (f4) lines, to be more precise..... Jim said: That would be your infrared focus point. If you use infrared film, take the focus point at the regular focusing mark and turn the focus ring until that point lines up with the red dot which you described. For regular film, pretend the dot isn't there. :) Jim _________________________________________________________ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com
