Here's the question:
If I want to take a tack sharp image of the wall in front of me and I put my lens to its near focusing end and the marking on my lens says say 0.9 m, to which bench mark on the camera do I have to measure the distance (asuming the lens is perfectly aligned)? The film plane, the lens front element or somehwhere in-between? |

Hello Bernd Ebach.
The Film Plane Is the point to measure the distance.

Clive is correct, that is the normal standard.
If you are using an add-on closeup lens, however, you set your camera lens to infinity and measure from the plane of the closeup lens.

I'm not sure all cameras measure from the film plane. Those that do often have a film plane line engraved on the top cover of the camera. If you don't see a line check other sources of info as rto where to measure. |

Actually, the focus distance for all cameras should be measured from the film plane, except in the case Rick mentioned above. Just because the manufacturer omitted to include a film-plane indicator on the camera doesn't mean this isn't the proper place to measure from. (For instance, none of my Commie cams--former Soviet Leica-copy rangefinders--have such marks, but they measure to the film plane just like any other camera.) |
