Title: Inconsistency of lens information between [Panasonic] and [Composite] groups
Post by: Fodoh on October 28, 2023, 09:26:03 AM

Hello,
I have an inconsistency of lens information between [Panasonic] and [Composite] groups.
Here the filtered information regarding "lens" of exiftool v12.69 with options -G1 -a:

Code Select

[Panasonic]     Conversion Lens                 : Off
[Panasonic]     Lens Type                       : LEICA DG SUMMILUX 25/F1.4 II
[Panasonic]     Lens Serial Number              : 31102262
[Panasonic]     Lens Firmware Version           : 0.1.2.0
[Panasonic]     Lens Type Make                  : 2
[Panasonic]     Lens Type Model                 : 39 10
[Composite]     Lens Type                       : Unknown (2 39 10)
[Composite]     Lens ID                         : Unknown (2 39 10)

In the [Panasonic] group the lens 2 39 10 is known and converted to "LEICA DG SUMMILUX 25/F1.4 II" whilst in the [Composite] group the conversion is "Unknown (2 39 10)".

For another lens the situation is similar:

Code Select

[Panasonic]     Conversion Lens                 : Off
[Panasonic]     Lens Type                       : LEICA DG SUMMILUX 9/F1.7
[Panasonic]     Lens Serial Number              : XA250002G12K
[Panasonic]     Lens Firmware Version           : 0.1.0.0
[Panasonic]     Lens Type Make                  : 2
[Panasonic]     Lens Type Model                 : 41 10
[Composite]     Lens Type                       : Unknown (2 41 10)
[Composite]     Lens ID                         : Unknown (2 41 10)

Omitting the options -G1 -a does not help.

Please let me know in case I need to change some cli options. But imho this is a bug in this great powerfull exiftool. Please let me know in case you need the image.

Hi Fodoh,

What model camera is this? Can you provide a sample image?

Hi Phil,
it's a Panasonic Lumix G91. Here a sample image:

PS: I have other Panasonic and Panasonic/Leica lenses where this inconsistency does not occur.

PPS: The same inconsistency occurs with the Lumix G9.

Excellent, thanks. The Panasonic:LensType tag that gives the lens model is a string-type tag. I hadn't yet seen the numerical values for these two lenses, so I will add them to the table. Because these are micro 4/3 lenses, they will appear in the Olympus LensTypes table (https://exiftool.org/TagNames/Olympus.html#LensType), and will fill in 2 missing entries very nicely. ExifTool 12.70 will support these. If you find any more unknown lenses, please let me know.

P.S. I'll name them as follows:

Code Select

    '2 39 10' => 'Leica DG Summilux 25mm F1.4 II Asph.',
    '2 41 10' => 'Leica DG Summilux 9mm F1.7 Asph.',

(the Panasonic:LensType string doesn't say "ASPH.", but it seems this is part of the official model name according to the Panasonic web site.)
