I carry around some post-its and a pencil, - write down the lens, take shot of it and start shooting, if I need to make a next note - cross out the previous one, take another shot and so on until you fill it up. |

On my old Fujica AX-5 I had a "Photo Recorser", which was a replacement back for the camera which allowed one to "write" a few details directly onto the negative itself, via a stylus connected to a parallelogram linkage with a little LED at the other end.
Definitely a solution looking for a problem! |

If i want to record the aperture used during my normal work, i prefer to make two "identical" images, one wide open, the other at the useful aperture. From the differences in shutter speed - recorded by the EXIF - i can deduct the aperture easily and quite precisely.

I write in a notebook. The blank frames are an additional precaution. _________________ Dedicated to using manual focus lenses with digital.

That's what I recently do but less strict. With Auto ISO set it needs a bit more calculating too.
Most of my lenses have been adapted or converted to EF mount (including MD and CS) so focal length for them is already reported by EMF chips glued on their mount (for mounting on MC-11 to A7RII). The MC-11 adapter has some issues with the max. aperture transfer set in the EMF chip though. Odd enough with a Kenko 1.4x tele extender in between the max aperture x2 number is transferred. Chips that can not be programmed transfer the max aperture though, small choice though; 50mm 2.0 or 1.4. Lenses of the same focal length get a slightly different focal length set in their chips, according their viewing angle difference. IBIS acts accordingly and the Exif files tell enough to add the right description + settings now. So far I kept 5.6 as the general working aperture but I will try your method more.
Waiting for programmable chips for the Sony mount. _________________ Met vriendelijke groet, Ernst

To me, documenting the f/stops when testing a lens is at least half the point of doing the testing. The other half is examining resolution and contrast. _________________ Michael

I often record a short video after a series of test photos, using the camera as a glorified taperecorder. So I just describe the lens used and the settings, quick and dirty. This means the video is organised together the photos in Lightroom, and I add the relevant data by hand. |
