Luong's page which has an article explaining what to do. Although, I am most definitely stumped as how to approach this. While I am not looking for all the answers, I would just like to know if anyone has done it before and has any pointers to share. Thanks for listening! |

To find the near, far and hyperfocal distance for a specific lens, enter the focal length (mm), aperature (f/number) and the objects distance (whole or decimal number in feet). I searched for it on the internet and it has either moved or is no longer available. I do have Depth-of-Field tables for the following focal length lenses... 101mm, 135mm and 152mm. Will these help you? Harry |

BTW, that dig was in good natured fun. I have a Crown, Hassey 500C and a Nikon F5. I think they each have their place in application, but I gotta admit; I ONLY grin when I use the Crown! |

I just thought that it would help ease the transition from using a camera that practically takes the picture for you, to a camera that makes you think before you shoot. This is my first lf camera, and the big negs make me feel like a hero. As far as 'bells and whistles' go, I like having 4 different viewfinders. Also being able to disassemble the thing is a big plus for me. I hope i have mine long enough to give to my children. |

Here is another good site for DOF and focusing when not using the Crown as a normal fixed camera. <!--BBcode auto-link start--><a href="http://fox.nstn.ca/~hmmerk/">The <b>how to</b> of LF focusing & DOF</a><!--BBcode auto-link end--> |
