Lightroom Classification of Leica Lens

[ornate_wrasse]

I was processing some images I captured with my M9 in Lightroom 5. I only used two lenses that day. One of them was my beloved Nikkor SC 50mm 1.4, which of course is not a Leica lens, and the other was my Leica 28mm 2.8 Elmarit.

In Lightroom, it surprisingly identifies the lens as a Leica Summilux-M f/1.4. And, if that wasn't a bit crazy to read that my Nikkor 50mm 1.4 had become a Leica Summilux, it also identifies the images shot with my Leica 28mm 2.8 Elmarit as a Leica Summilux-M f/1.4.

It doesn't affect my images, so I'm not hugely concerned, but I wondered how Lightroom 5 can misclassify a lens used for an image.

Does anyone have any idea about what's going on here?

Metadata from 6-bit coding, or perhaps the lack of it, or just a "guess" on the part of the software, or maybe just a default.

The lenses I'm using don't have 6-bit coding.

^ that sounds about right to me

M9? I bet you have lens detection set to manual and manually selected the summilux. In this case alle lens changes and 6bit codes are ignored.

I'll have to check if lens detection is set to manual on my M9 and, if so, what lens is selected.

Sounds like this could easily be the reason LR displays it as a 50mm Summilux

Thanks for the tip!

Lr doesn't "detect" the lens used. It merely reports whatever crib note the camera body scribbled in the appropriate field in the metadata. If Lr reports the lens incorrectly it is because the camera wrote incorrect data.
