Develop Persona does not identify correct lens

[Nikkor Shooter]

I noticed that the incorrect lens profile is being used in the Raw Develop Persona.

I am running 1.7.1.404 in Windows.

My camera lens combination displayed above the raw image in Develop Persona is:

·         NIKON D800 (AF-S VR Zoom-Nikkor 70-200mm f/2.8G IF ED)

My camera lens as purchased in 2005 is:

·        AF-S VR 70-200/F2.8G IF-ED (Nikkor)

Yet under the Lens tab on the right of the screen the lens profile shows:

·         Sigma 70-200mm f/2.8 EX DG APO OS HSM.

Clearly this is incorrect so I went to your video tutorial headed “Affinity Photo – Adding lens profiles” and downloaded the Data db file from GitHub/Lensfun.

This was then loaded via Edit/Preferences/General/Open Lens Profile Folder.

Affinity Photo was then restarted but unfortunately the displayed Lens profile in the tab still shows the incorrect Sigma lens.

Clearly the overall technical specification is similar for both lenses, but the optical corrections are fundamentally incorrect; so rather than improving the image I’m adding another layer of distortion to an already imperfect rendering!

I can understand why Affinity Photo / GitHub/Lensfun may not correctly identify a 14 year old lens, but I don’t understand why it would wrongly identify a completely different manufactures lens!

Why it is that Affinity Photo does not install the correct profile?

Can you please link me to one of your RAW files that you're opening so I can get this looked into.

Thanks for coming back to me.

I have attached the two Nikon Raw files I used.

Kind regards

Thanks Chris, I've passed the .NEF files over to our developers, they will help in resolving the issue. For the moment, you can disable the Lens Correction in the Develop persona, when in the Photo persona apply the Lens Correction Filter from the Filter dropdown menu and the Nikkor lens should be available.

Thanks Lee

I will do as you suggest.
