[Fixed] Lens correction profile mismatch

Recommended Posts

I am using a Nikon D5600 with Nikon kit lenses 18-55, and 55-200. In Develop Persona/lens the correct lens correction profile is shown for the 18-55, but for the 55-200 it shows as a Sigma model 55-200. I checked the list of lens correction profiles in this forum (Patrick Connor Dec 2018) and found both my Nikon lenses listed, and a Sigma one of similar spec:

Nikon AF-S DX Zoom-Nikkor 18-55mm f/3.5-5.6G ED
Nikon AF-S DX Zoom-Nikkor 55-200mm f/4-5.6G ED

[wrong one]: 

Sigma 55-200mm f/4-5.6 DC

Can I get Photo to see the correct profile somehow, or is this a bug?

Sorry, I should have mentioned that this query came up whilst using the 1.7 Beta. I checked that I am using the latest patch.

After Walt's comment, I went back to my paid-for 1.6.7 AF Photo to check how that worked. In both iterations the lens name is correctly reported in the info strip along the top of the working window. In both versions lens correction can be switched on in the Assistant options; in 1.6.7 you can't tell what it is doing except for the change in the image if you can spot it.

In 1.7 beta you can manually switch on the lens profile in the lens tab in the righthand develop studio panel. There is a drop-down. With my 18-55 "normal" lens this drop-down matches the spec in the main window header, but with the 55-200 the drop-down reports a Sigma 55-200 profile whilst the main window header shows the correct Nikon 55-200 name. When clicking the profile on-or-off you can see the image shape pop in and out. So I don't know if this is a good result or not.

I must go and photograph a brick wall with both lenses and check against the grid overlay in the app. ;-)

Thanks. Here is a file taken recently with Nikon D5600 and Nikon 55-200 lens which shows a Sigma lens name in the "lens" tab in the develop persona Right-hand Studio sidebar. Lens description in the strip along the top of the main window is correct.

Hi GeoffM33,
An update on this: the wrong Sigma profile doesn't appear listed anymore in Affinity Photo Customer Beta 1.7.0.123 (Lens tab). Currently we don't have a lens correction profile for the Nikon AF-S DX Zoom-Nikkor 55-200mm f/4-5.6G ED lens thus none appears there.

Hi,

I just installed the new App Store version of Affinity Photo 1.7 and found James Ritson's tutorial on lens profiles. I found the GitHub database and loaded the Nikon SLR file into AP. But AP is still loading the Sigma profile incorrectly. I dug into the LensFun database and found the correct profile for my lens, but AP is finding the Sigma one first. Hmm...

Hi GeoffM33,
Unfortunately we had to revert the fix because it was causing issues with other lenses. The original issue/report remains open to be looked at/fixed, it will just take some more time. My apologies for the inconvenience this is causing you.

OK. No worries. I'll use the distortion slider as necessary for now. But I guess the lens profile data is more complex than just pincushion/barrel effects?

I also noticed that my Tamron 18-400mm lens was not getting a profile set so I also followed James's instructions to load a new set of profiles.

I looked inside of the slr-tamron.xml file and I don't see any information regarding my lens.

Who creates these files?

Can I get the proper numbers from somewhere and add that information to this file?

Thanks for you help.

Thanks for your help with this bug. We have now resolved the problem and will make the fix available in the next release of Affinity Photo on your platform.
