Request: Olympus 8-25 mmf4 Pro lens profile

[GSMW]

The most used lens on my Olympus E-M1iii is the 8-25mm f4 Pro. Is there any possibility that a profile for it could be included in a future release?

See the Lensfun database (which APh uses), according to that a "Olympus M.Zuiko Digital ED 8-25mm f/4.0 PRO" is already supported, though no vignetting ...

Can you share one of your RAW images with us?

You're looking at the "develop" list (daily build), not the latest released version (3.3), I think. I don't see it in the released list, which is what Serif is probably using (though they might have grabbed the develop version when they built 2.1.0.

Since it's in develop, that should mean that users can get the info from the database and install into Affinity Photo themselves, though.

There's no need for this, you can fetch Olympus RAW samples shot with that lense already from here if some are needed ...

That's why I referenced the Lensfun repository here, people can at least update lensdata themselves!

Try this xml in your lens profile folder, it works in V1

Thank you for the file. It seems to function in V2.

[David in Яuislip]

It's all a bit odd
I noticed that this lens was missing when I trialed the V2 version back in November, thinking that the lensfun download had gone awry I wrote this query
https://forum.affinity.serif.com/index.php?/topic/172674-issue-with-the-lensfun-data-transfer-for-photo-v2-which-is-quite-recent-nov-2022/#comment-990704

I can't find a list of supported cameras/lenses later than 19 September 2022 but I'm staggered that it's not available in V2.1.1
I suspect that not many people with this lens use Photo for raw development, I certainly don't
Anyway, at least you're fixed

@David in Яuislip

I think that only 4 or 5 members of the Camera Forum that I'm in use Affinity Photo, the rest are all using rent ware.

[David in Яuislip]

It would be interesting to ask the other Affinity users whether the 8-25 lens is available in their versions. I consider the raw abilities of Photo to be one of its weakest features, if I only had Photo for raw development I'd go back to shooting jpegs

Thanks, but I prefer samples from the user having the discussion, to make sure I see what they are seeing.

Also, the issue might be that the camera embedded the lens info incorrectly, or that the user specified the lens info incorrectly, so having an image from the camera in question can provide useful information for diagnosing the problem.

I don't have a profile for my 8-25mm/4 lens, but use the 7-14mm/2.8 with usable results. In the meantime, I no longer have an M43 system, but only use my Nikon Z6II camera and some Nikon lenses. Although the result of the develop persona is not so bad but is the weakest part of the affinity photo.

I too have Affinity Photo 2.1.1 and use an 8-25mm F4 PRO lens. It does not show up so far. I managed to get the XML linked above but I have no idea where the Lens profile folder is located in Windows. Can anyone give me a steer?

TIA

Welcome to the Serif Affinity forums.

In Photo, Edit > Settings and click the button at the bottom of the dialog.

[Crispyweet]

Thanks so much. It's in the user profile location then. Also I can report that the lens is not only now listed but also auto detected too.

I am a little curious where the XML file came from too?

Thanks again,

Chris

Usually they have been downloaded from the Lensfun database, which is what Serif pulls the data from periodically.

Thanks Walt!
