Develop Persona not automatically making Lens Corrections

[Tim in the North East]

I use Affinity Photo 1.10.4 on an Apple iMac with 3.3 GHz Quad-Core Intel Core i7 and using OS Monterey 12.2. The problem described below also happened when I was using OS Big Sur.

One of the lenses I use on my Nikon D750 is a Nikon AF-S Nikkor 24-85mm f/3.5-4.5G ED VR.

When opening RAW images on the Develop Persona, Affinity does not automatically apply the lens correction - I have to do it manually. Affinity reads the EXIF data for the lens and knows it is the 24-85mm lens - it just does not automatically apply the lens correction. 

This contrasts with my other Nikon lenses (17-35mm and 70-300mm) where the lens correction is automatically applied to RAW images when they are opened in the Develop Persona.

Is there are fix to this problem?

Can you provide a sample RAW image from that camera with that lens, Tim? It is possible that the lens information is not identical to what Photo expects.

This may not matter but in the Development Assistant which RAW Engine are you using? If you switch to the other one, does anything change?

The Develop Assistant sets the RAW Engine to 'Serif Labs' and Default lens profile to 'Auto select'. Sadly changing the RAW Engine to 'Apple (Core Image RAW)' does not make any difference - Affinity still does not apply the lens profile of the Nikon 24-85mm lens.

Hi Tim,

Welcome to the forums

It seems as though that lens is on our supported list so everything should be fine. If possible could you provide a copy of the problem RAW file so I can try replicating this issue? If you would rather not post it publicly please let me know and I will provide a link to our DropBox.

Thanks

Thanks to all who have replied. Here is a RAW image taken with the Nikon 24-85mm lens - if you are interested the location is Sunderland Docks in North East England,_DSC4298.NEF

Thanks for the sample, @Tim in the North East.

Your Lens is not quite the same one that is in the list of Lens profiles.  Note that yours has VR on the end; the built-in lens profile does not have that designation:

That may explain why it was not automatically selected. (But I will freely admit I do not know how the matching is done, or how exact it needs to be.)

Many thanks for spotting that! Is this something that Serif would fix in the next upgrade of Affinity Photo? How does one bring it to their attention?

 

Cheers

If it's all working correctly: Serif uses the lens database from the Lensfun project. If someone updates that to recognize your lens, then Affinity Photo would pick it up when Serif next refreshes the lens list. There are also instructions at that site for taking your own test images and calibrating your lens, and updating the Lensfun database. Or you might find there's an update there you could download and install in Photo yourself.

However, if there's something wrong, and that entry should be used for your lens automatically, then that might take a code change somewhere (Lensfun, or Affinity).

I don't know which is the case, as I don't know if there are VR and non-VR versions of that lens.

Possibly @Callum or another of the moderators will be able to provide more information.
