I noticed something quite strange while editing photos shot on my Leica M11. The lens that PL6 reports for the image differs depending on whether it was shot with LiveView on or off. Note that this isn’t just cosmetic. PL6 seems to on correctly detect and enable the Optics Module ONLY FOR images shot with LiveView on, which is quite annoying.
To illustrate this, I’ve attached two images. Both were shot on the same day, same camera, same firmware version. The only difference again, is that one was shot with LiveView and the other wasn’t, and the camera was powered off between the two shots.
I used exiftool to dump the metadata, and it gives the same Lens ID value for both: Apo-Summicron-M 1:2/50 ASPH., same as what PL6 reports for the non LiveView version.
Please help. I’d like to be able to us the Optics Module for all my images!
The difference can be caused by a glitch when the files are written in camera or by a systematically different way to register the values depending on whether LV is on or off. You can find out if the difference is systematic by taking a few shots with the same settings in both modes and see what the resulting files report…
…nevertheless, the camera has no way to register the aperture automatically. Maybe the f/1.0 throws DPL off, in which case you’d want to follow @Egregius’ advice.
As Leica M-lenses don’t feature electronic contacts, the “interpretation” of the aperture by a mechanical control curve between lens and body might be misinterpretd/affected by a firmware bug. After all, it’s only Leica and the company is not too well known for their state of the art electronics.
