[PHOTO all Versions] Lens Profiles Went Wacky

[Ron P.]

I noticed the RAW Lens Profile went wacky, in all versions of AP. Prior to the recent update, they were correct in auto-detecting, choosing the correct lens for my CR2 files. It says the lens used was a Nikkor, a Nikon... Oh those are fighten' 😡🤣 curse words for a Canonnista, (Canon shooter). Besides the lens is a Sigma 150-600mm Contemporary. Any photographer that has a little knowledge of DSLRs, knows you can not use Nikkor lenses on Canon bodies..

Something happened to the Lens Profiles, AP always selected the proper lenses for me until now.

[Ron P.]

I've done further testing on this, and discovered my Sigma 150-600mm and Sigma 17-50mm lenses are the only ones AP mistakenly detects as Nikon. My other lenses, Canon 100mm macro, Tamron 70-300mm and Sigma 70-200mm were correctly detected. Those 2 Sigma lenses have been correctly detected until recently.

Also I need to further investigate the Removing Lens Vignette. For those 2 lenses it doesn't seem to work.

Can you post raw files with the lenses that don't work and I'll try them here?

I get a similar problem, my Sigma 18-300mm F3.5-6.3 DC Macro HSM lens is detected as the Sigma 18-35mm F/1.8 DC HSM [A] for Canon mount in both V1 & V2. The metadata from the camera as shown by Digital Photo Professional software (DPP) from Canon is correct. However all the data in both versions of Affinity Photo displays the incorrect lens even in the metadata. The interesting thing is that in the list of lenses the Sigma 18-35 is the next lens to the Sigma 18-300 thus I suspect the data for the 18-300 is incorrect and being attributed to the Sigma 18-35 in the dataset. One for the developers to check I suspect!

Ok, here you go. FWIW, I'm finding there are some AP correctly detects.

Kinda of odd, you're having problems with Sigma lens too.

Since I discovered this issue, I've reinstalled AP-1, and AP-2. With AP-1, the issue seems to gone away, it correctly detects those lenses now, but with AP-2, (which I've not updated to the 2.0.3 since reinstalling), still says those lenses are Nikkor. I just checked right before I uploaded them.

On both images

2.0.0 detects the lens incorrectly (Apple iPhone!!!)

2.0.3 beta, detects the lens correctly

[Ron P.]

I spoke too soon earlier when I stated that AP-1 the issue has gone away. Nope, still there, launched it and checked several images, and it too, thinks those lenses are Nikkor.

I'm not sure where AP-2 grabs the Lens Profile data. I've checked the .affinity path, it has a Lens Profile folder, but it's empty. For AP-1 the Lens Profile folder is in the Program Data>Affinity>Photo>1.0 folder.

[AlainP]

Here 2.0.0 and 2.0.3 beta display the correct lenses.

Both images select a lens automatically in Photo V1 but I think the 150-600 is wrong, see the long boring story below:

ExifTool Version Number         : 12.41
File Name                       : IMG_0187.CR2
Lens Type                       : Canon EF 100-400mm f/4.5-5.6L IS USM or Sigma Lens - weird or what???
Lens ID                         : Sigma 150-600mm f/5-6.3 DG OS HSM | C or Sigma 150-600mm f/5-6.3 DG OS HSM | S
Scale Factor To 35 mm Equivalent: 1.6

There are three such lenses in lensfun https://github.com/lensfun/lensfun/blob/master/data/db/slr-sigma.xml
  <maker>Sigma</maker>
  <model>Sigma 150-600mm f/5-6.3 DG OS HSM | C</model>
  <mount>Canon EF</mount>
  <mount>Sigma SA</mount>
  <mount>Nikon F AF</mount>
  <cropfactor>1.534</cropfactor>
  <!-- Taken with Nikon D7200 --> which has no vignetting data

  <maker>Sigma</maker>
  <model>Sigma 150-600mm f/5-6.3 DG OS HSM | C</model>
  <mount>Canon EF</mount>
  <mount>Sigma SA</mount>
  <mount>Nikon F AF</mount>
  <cropfactor>1</cropfactor>
  <!-- Taken with Nikon D800 -->

  <maker>Sigma</maker>
  <model>Sigma 150-600mm f/5-6.3 DG OS HSM | C</model>
  <mount>Canon EF</mount>
  <mount>Sigma SA</mount>
  <mount>Nikon F AF</mount>
  <cropfactor>1.613</cropfactor>
  <!-- Taken with Canon EOS 80D --> which has vignetting data and is used for the attached Sigma150-600.xml file, however the Remove Lens Vignette slider does nothing

If you put that into the Lens Profile Folder it will be selected on opening a raw file, you can see
Sigma 150-600mm f/5-6.3 DG OS HSM | C rather than the built-in
Sigma 150-500mm f/5-6.3 APO DG OS HSM.
Oddly lensfun doesn't show APO for that lens so dunno where that's from. The new profile has a slightly tighter crop and different correction but which is more accurate is beyond me, maybe take a snap of a brick wall to see

ExifTool Version Number         : 12.41
File Name                       : IMG_0024.CR2
Lens Type                       : Canon EF 85mm f/1.2L USM or Sigma or Tamron Lens - more weirdness
Lens ID                         : Sigma 17-50mm f/2.8 OS HSM or Tamron SP 17-50mm f/2.8 XR Di II VC (B005)

On opening a raw file, you can see Sigma 17-50mm f/2.8 EX DC OS HSM is selected, there is a  difference between this and the built-in version as the screenshot shows but they both introduce barelling for your image and I prefer it uncorrected, effect probably varies with focal length, zip file contains jpegs of both

@David in Яuislip, Thanks for the files. I tried them but got the same result.

I think I finally discovered what's happening. AP is misreading the XMP sidecar files. When I first shot the images, I developed them in LR 6.14ish version, and had XMP sidecar files produced. So today I disabled the Load metadata from XMP sidecar files (in Preferences). Opened several of the files known to give the wrong lens, and now I get the correct lens selected automatically. Also for files that did not have XMP files, AP detected the correct lenses.

The XMP files are not the problem, because other programs, like PSP give the correct lenses.

I've attached the XMP files for the images I uploaded before, if someone wants to test my theory..

Thanks

Looks like the xmp has overwritten the cr2 file lens data, unusual for Lightroom to make a cockup but there's always a first time

Just checked after installing latest update V2.0.3 and still have the same problem....not fixed but I note some have been?

Have you tried disabling the Load metadata from XMP sidecar files in the Preferences for AP ? It's found at the bottom of the General tab.

I hadn't but I have now and it made no difference unfortunately, thanks for advice.
