Exit Pupil Distance

The position of the exit pupil has a big effect on how well a legacy lens will perform when used with a digital sensor instead of film. This article on the Lensrentals blog has a good explanation of the effect, and also contains a table with the exit pupil distance for many lenses.

To expand that table, I recently started to measure the exit pupil position of lenses I had access to. My measurements are not that precise, so the numbers might differ from those in the Lensrentals article by up to 1-2mm. In cases where it was particularly hard to measure, the number is prefixed by a tilde. With CPU lenses, Nikon cameras record the exit pupil position in the EXIF data. I have listed values obtained this way in the third column. Here is a table with values obtained from EXIF data.

The value in this table is the exit pupil position at infinity. Classic lenses focused by extension have larger values for near subjects, but lenses with internal focusing often reduce their focal length for closer subjects and might have a lower value than at infinity.
