Fujifilm GF20-25: Randunschärfe bei RAW-Entwicklung

Fehlerbeschreibung:

Die RAW-Entwicklung in LrC führt zu Bildern mit unscharfen Rändern.

Fehler tritt auf bei Bildern, die mit Fuji GFX100s und GF20-35 mm erstellt wurden. Bei anderen Objektiven tritt der Fehler nicht auf.

Die Unschärfe ist bereits in der Ansicht der RAW-Dateien erkennbar.

In der Kamera erstellte JPEG-Bilder sind in Ordnung. Der Unterschied ist klar erkennbar.

Bilder wurden vom Stativ, mit Selbstauslöser und abgeschaltetem Stabilisator erstellt.

Fehler tritt sowohl auf M2 als auch i7 Rechnern auf.

Versionen:

LRC 13.4

Camera Raw 16.4

macOS Sonoma 14.5 / M2 chip // macOS Sonoma 14.5 / Intel i7

Die angehängte Dateien "SCHARF.PNG" (in der Kamera erzeugt) und "UNSCHARF.PNG" (Export aus Camera Raw) zeigen den Randbereich des Bildes. Das JPEG aus der Kamera ist schärfer und zeigt auch die weißen Flecken in den schwarzen Bereichen des Testbildes.

Mache ich irgendeinen Fehler bei der Bearbeitung der Bilder oder wird möglicherweise das Objektivprofil nicht korrekt umgesetzt?

Vielen Dank schon mal vorab für alle Hinweise.

Please upload a sample raw file to Dropbox, Google Drive, or similar and post the sharing link here. Adobe isn't likely to pay attention unless they can easily reproduce the issue.

Sample files

File# 2914: Focus on center of left star

File# 2915: Focus on center of middle star

Bild# 2916: Focus on center of right star

All SOOC-Bilder are created in camera.

I tried to apply sharpening to RAW files to get same results as SOOC. But edges are still softer.

In the above copy of your screenshot. You stated in Camera. Is that actually in LrC?

1. If you turn that off, does the image behave differently.

2. Might be a language difference. In my copy I do not have Standard. What are your options?

3. The info not shown. Anything about Built in profile (probably not for the Fuji GF series) or any error?

I see that you used Adobe Camera RAW to demonstrate the issue. As opposed to showing the result in LrC. At any rate this appears to indicate a issue in the RAW engine, both internal to LrC, and the plug-in used in PS.

I assume, if you continue in PS and apply that Camera RAW result, the image in PS also fails???

You may want to post in the Camera RAW community.

If you do so, include a statement that you have posted the above in the LrC community. Include a link. Some might argue this is double posting. Some might argue that the posting should be moved to Camera RAW. In this case, I think (IMO) go ahead and post. Not an Adobe employee

Thanks a lot for your reply!

In LrC the tool is "Lens Corrections".

In case I untag "Enable Profile Corrections" there's lots of distortion. So Profile Correction definitely needs to be applied.

Setup options for Profile Corrections are

- Default (Standard in german)

- Auto

- Custom

There are no errors when using Profile Corrections Default.

Sorry for uploading screenshots from Adobe RAW instead LrC. There is no difference when using LrC. PS also shows same results.

Zusatzinfo: Abschalten der GPU behebt den Fehler nicht.
