Quick fix for lens info written in different formats

[lippe]

Over the years, i have used some different type's of camera's and lens combinations and i want a quick way for have the in a temporary collection.

I noticed the number on lenses listed in the technical details is more that i can afford.
The same lens is listed as '70-200mm' , '70-200 mm' , '70.0-200.0' , 'EF70-200mm f/4L USM' , 'EF70-200mm f/4L USM5 USM'
I conclude the lens information in not written correctly, or not in the same way. Probably i used different software: IDimager 3-4-5, Photo Supreme 1-2-3, Lightroom 2-4-5, DiVU, FPV, DPP, ???

My first idea was the create a private label for the lenses is own. So i have them faster at my disposal to create dynamic searches in conjunction with focal length. But i noticed sometimes the lens information is not show in the info panel. The info panel uses the same info exif/xmp info as the Catalog Explorer > By Image details > technical section.
So i want a quick fix for lens info written in different formats. I don't like to make changes in the raw files, updating the xmp in side-car and jpg is fine. So i have the corrected information also outside Photo Supreme.

I would first try a "Convert Metadata to XMP". That will re-read the technical metadata from Exif and write it to XMP. Of course it could also be that the files themself contain inconsistent lens info and in that case my suggestion won't give much improvement.
You can also select all the files, and update the Lens Information by hand in the Image Details->Technical. That field should be editable.

Hert,
I verified the same lens on two different cameras, both cr2 raw files where the exif is untouched:

Like you expected, the older camera did not write detailed information about the lens.

Then i have to try update the lens information in Image Details->Technical. Photo Supreme will not update the information in the maker notes.
Will Photo Supreme update/create the exif 'Lens Model'? If i hover the lens information field i see '%xmp:aux:lens'

[Hert]

aux:Lens will be written to Exif as tag 0xA434

This Exif 2.3 spec tag is the highest in the pick-order to determine lens information (also higher than the lens info in maker notes).

[lippe]

Hert, i started to test with the one cr2+jpg, but the exif tag' 0xA434' does not exist before i updated in the 'lens information' (in Details > Technical section), so Photo Supreme has nothing to update in the exif section. You already provided the reason, the tag' 0xA434' is only in Exif 2.3 spec.
Forcing the tag with exiftool is maybe possible but this isn't a quick fix anymore.
I have to be careful because using the 'Convert Meta to XMP' will undo the changed 'lens information' in XMP.
I noticed this topic in the older forum, where a registry tweak is suggested to prevent reading maker notes to compose the lens value. Even Photo Supreme possibly still support the tweak, this is all to much effort.

I have to live with fact the lens info is not available for older images, and created special labels for lens information. I used technical details to search all image that used the same lens manually to assign the label. But now i have to to this for every new image that i import.
If i use dynamic search based on the technical '70-200mm' , '70-200 mm' , '70.0-200.0' , 'EF70-200mm f/4L USM' , 'EF70-200mm f/4L USM5 USM', the search will always up-to-date; also for new Images. But how is make the use easier? I can't assign a label based on the dynamic search? I can put that dynamic search to the favorites... but the more items i put in the favorites, they getting unclear.

Feel free to vote for FR 2643 to support favorites (dynamic queries) inside hierarchical portfolios.

[lippe]

Oh... i was expecting this was already possible. Thank you for link. I voted +1
We don't have to re-enter a request that didn't make it in V1 or V2... no Hert just focus on the items that likely will be used by more people.
And Dynamic Search is something the beginning will use quickly. Maybe is your FR will make it,Some example 'Smart collections' could come with the new Photo Supreme version. Make it more clear how to use it.

[Hert]

Lippe, when you sync to the file, I do expect that the tag I mentioned is written to Exif

[lippe]

Hert, i did sync the file, otherwise i cannot verify what is written to the file in Exiftool. But the tag 0xA434 is not in the exif.
I entered ' EF70-200mm f/4L USM' and this is only updated in XMP > Lens
This is also what i'm see in Phoot Supreme > Details > XMP Advanced.
