S1Rii saves MF lens info in EXIF data

As soon as the lens information was entered, saved and selected manually in the body of the S5II, that complete information (lens name, focal lenght - in my case FFL i.e. Pentax HD 43mm) should also show up in the EXIF data of the jpeg. But it does not with my S5II.

Strangely the Exif data of my Jpeg only shows the FL which I entered manually in the body, but not the lens name. I.e. only "43mm". But nothing else.

I've just tried this with a new manual lens on my S5ii, and the name I give to it is displayed among the EXIF data (displayed by DxO Photolab in my case).
 
ok, it shows here the correct EXIF data. But not in Windows. That is very strange.
It will show up in Windows, just not in Windows Explorer. As I mentioned above, Windows Explorer has a very limited ability to show EXIF data.

But there are fields in Explorer for this.

It neither shows it in the photo display app of Windows 10. Only in Lightroom and here in the forum with the special Exif data forum plugin.

Interesting. This may be the result of the fields to which the EXIF data are written. Based on my EXIF reader (gThumb), the description of a Panasonic or Sigma autofocus lens is written to two locations: (1) the EXIF Maker Notes in a field labeled Lens Type, and (2) the EXIF Other section in a field labeled Lens Model. On the other hand, with a manual focus or adapted lens the description of the lens is only written to the second location: the Lens Model field in the EXIF Other section. Windows Explorer and Photo Viewer may only be searching for the lens in the Maker Notes section, in which case the software will miss it. It seems that better programs such as Lightroom (or the forum software) will search the entire EXIF stack. This is just speculation on my part; I don't know enough about Windows or EXIF data to provide a definitive answer.
 
Sounds logical to me. And an idea for a firmware update to make sure that the manually entered information in the camera will be written in both EXIF data fields. That would solve the problem.

I don't know if that would be permissible. I seem to recall that the Maker Notes section is reserved for data embedded in the lens by the manufacturer. I believe that is why all such entries are blank for "dumb" lenses, and why there is the EXIF Other section, which is unrestricted. If I am correct then Panasonic is doing things by the book, and the problem needs to be fixed by Microsoft.

Win 10 photo app.......

Windows "10" is not a regular state of the art Widows version. So more obliviously it doesn't show the actual today’s correct EXIF data.

Till "now" (but I don't use the latest new camera models - neither their latest camera's "EXIF" data implementation).
I always go back to an "old" EXIF reader by "Phil Harvey". Old but still the best, by software updates till "today".

By combination with the ExifTool User GUI.

Be very careful using ExifTool with S1Rii RAW files. The latest production release of ExifTool is 13.25, which can corrupt S1Rii RAW files. There is a pre-production release (13.29) which corrects this, and includes the following note: "Fixed issue where RW2 images from the Panasonic DC-S1RM2 could be corrupted when writing". In short, pay close attention to the version you are using, and don't just use the latest production version.

ExifTool is a very powerful program, but because it is an EXIF editor it has permission to re-write your files. While I have used it in the past, unless I need to edit the EXIF data for some reason I much prefer to use a simple EXIF viewer for examining EXIF data. Less chance of something going wrong. :)
 
Thanks for this extra clarification.
But as noticed. I am am not using the latest camera models. And (nearly) never change / edit EXIF data. (Only reading)
