Lens correction issues in Photo RAW 2022.5
Answered
Hi there.
Since the update of Photo RAW to Version 2022.x I've got some issues with the new automatic lens correction.
Background: I'm using a Nikon Z50 with both Kit lenses (16-50mm and 50-250mm) and I also using a Meike MK35 (35mm) manual lens with the camera.
When I want to edit images taken with the Meike lens I cannot change the lens distortion. The slider does not do anything because PR didn't find the lens profile or something like this. Before the update of the new automatic lens correction everything worked as expected. Here's an example RAW image where you can check the behaviour (don't mind f/0 as aperture value because it's a fully manual lens) https://drive.google.com/file/d/1_TqXViuXYgwaPjTs7aPQW5MyTvp9HOo9/view?usp=sharing
Any ideas?
Best regards,
Christian

I'm told I have to request access before I can download the file.

Thank you for your request. I granted the access and changed the sharing so everyone should have access now.

I suspect the reason you can't do anything with it is because there is no lens information in the metadata for the image. The program doesn't have any data to work with.
I've been adding info via ExifTool but so far I haven't found the right field or combination of fields to get it to work. Possibly because even though I've identified the lens manufacturer as Meike and the focal length as 35mm (I'm using f/8 for my testing) it doesn't know what to do with a Meike lens.
You can download and install ExifTool (it's free) and continue to play with it yourself. I would also send support your file and report the issue to them. You'll have to give them the Google download link as the file will be too big to attach to the support request.

Many thanks, Brian.
I found another solution proposed by yourself in another thread: https://on1help.zendesk.com/hc/en-us/community/posts/360047790991-Lens-corrections-for-manual-lens-How-
This works really nice for me too here, because the Meike 35mm lens is in the Lensfun database, so I can trick PhotoRaw with a preset.
Regarding to ExifTool: I have it on every machine already and using it sometimes. Last very useful case was re-ordering my photos by creating directories based on the EXIF date and move them because I'm bad at keeping my folders clean so all images are in one folder ^^.Thank you again, even if you helped in a different thread!
