Change my lenses correction

Ricardo Sandoval · September 24, 2020

Hi;

I have some questions when I open a raw file in Affinty Photo:

The image is desaturated at all I don't know why.
The file have no information about the lens who I used, in the video attach you can see.... the camera was Sony a7MIII and the objetive was SAMYANG AF 85mm F1.4 FE (so this objetive must be automaticly detectec for the lens correction)
The last and most important is when I end the correction with my favorite profile of SAMYANG and go to Develop Persona in the name of the file the correction was changed to SAMYANG AF 35mm 1.4.

Can you help me with this doubts please and said me who can i solve.

Thanks in advance

Couple of things, Use the search function instead of looking in 'Favourites'. Type the name of the lens into the red area and you'll get a list.

and finally you can try to use the Assistant to assign the lens profile automatically. Go to View > Assistant Manager then choose the Develop Assistant...

I have some old Nikkor glass I use on my Canon so there is no lens information but I can still choose the correct focal length for correction. It is the focal length that is important, although I will wager that there are some zooms which really need the correct file.

You are welcome Ricardo.

Have you verified that the lens model contained in the EXIF data of the raw file itself is actually correct? It appears that it is not. Manually selecting a lens correction profile will not change the EXIF data for the lens. Is the firmware for the camera and lens up to date? You can use EXIFTool to change the lens data in the raw file manually to the correct lens and then see if AP will detect it and automatically apply the correct lens profile.

Thanks for your help Kirk

Hi,

You can download ExifTool (Mac or PC) here. It's a command-line utility which doesn't have its own interface and isn't installed in the normal Applications folder.

The MacOS version runs from within Terminal and there is a steep learning curve, so if you're not familiar with using the command line then you could upload a RAW file to this forum and others may be able to help to read the EXIF information.

An example of ExifTool returning lens data:

Cheers,

Ricardo Sandoval · November 4, 2020

this seems is a problem with the list of the lenses who have no profile for that lense.

In other sofware works well.

thx

Ricardo Sandoval · November 30, 2020

Any knows other solution to get an auto-select the profile lenses...

I have the assistant correct set up as OLD BRUCE said and my affinity not get any profile for any lenses.

I just try with other Samyang 14mm F2.8 AF and didn't work too... but in Adobe Camera Raw its get correct.

Please any help will be welcomed

Thx

walt.farrell · November 30, 2020

The lens info as reported in the EXIF information for the file must match the value in the LensFun database, or the profile cannot be correctly auto-selected. So you need to investigate what the EXIF data says, and what the LensFun data says. If the auto-selection is not working properly then there must be some mismatch.

If you supply one of your RAW images and tell us which lens you used someone here might be able to do that investigation for you.

Ricardo Sandoval · November 30, 2020

Hi Walt thanks for all this information...

Tomorrow I uploaded a photo and you can check this info please I don't understand so much all about exit I tried as other mate in the post said but I don't know if I did well.

Other things who could help is that Adobe Camera Raw recognize the lenses as "Rokinon 14mm 2.8 FE” who is the other name for Samyang lenses....

Thx

Hi @walt.farrell an all who can help me..

As i promised yesterday I attach the link to dropbox of two photos one with Samyang 85mm f1.4 FE and the second with Samyang 14mm f2.8 FE, both of them got it with Sony a7 III.

Thx in advanced your your help.

For Samyang 14mm f2_8.ARW the file EXIF data that seems relevant is

  Lens Type                       : E-Mount, T-Mount, Other Lens or no lens
  Lens Spec                       : E 14mm F2.
  Lens Mount                      : E-mount
  Lens Type 3                     : Samyang AF 14mm F2.8 or Samyang AF 35mm F2.8
  Lens Type 2                     : Samyang AF 14mm F2.8 or Samyang AF 35mm F2.8
  Lens ID                         : Samyang AF 35mm F2.8
  Make                            : SONY
  Camera Model Name               : ILCE-7M3

Photo identifies it by the Lens ID as SAMYANG AF 35MM F2.8.

The Lensfun database has two entries that are similar, but that do not match:

 <model>Samyang 14mm f/2.8 AE ED AS IF UMC</model>

One entry is for a cropfactor of 1, the other for 1.523. But note that that AF is missing.

--------

For Samyang 85mm f1_4.ARW:

  Lens Type                       : E-Mount, T-Mount, Other Lens or no lens
  Lens Spec                       : E 85mm F1.4
  Lens Mount                      : E-mount
  Lens Type 3                     : Samyang AF 35mm F1.4
  Lens Type 2                     : Samyang AF 35mm F1.4
  Lens ID                         : Samyang AF 35mm F1.4
  Make                            : SONY
  Camera Model Name               : ILCE-7M3

The strange thing about this one is that you have said it's an 85mm lens, and the Lens Spec field says 85mm, but the camera/lens is reporting the lens type and ID as a 35mm lens. The only entry in the lensfun database for a similar lens is this one:

        <model>Samyang 35mm f/1.4 AS UMC</model>
        <!-- This model is really only available for Nikon.  For the other
             brands, the 35/1.4 may have different characteristics. -->

Note that the model name does not match (which means that Photo won't find it) but also that this lens is only for a Nikon camera.

Result: Basically, both lenses are unknown to Lensfun, and you need to either wait for them to calibrate them and add them to their database, or you need to calibrate them yourself and provide the information to Lensfun for inclusion in their database. The Lensfun website has information about how to ask them to do the calibration, or how to calibrate them yourself.

Hi @walt.farrell thx so much for your help ill try contact with LENSFUN to try include this lenses in the database..

You're welcome, Ricardo.

You can persuade Photo to apply an existing, similar lens correction instead

Download the relevant fie from https://github.com/lensfun/lensfun/blob/master/data/db/mil-samyang.xml

Modify the model descriptions
<model>Samyang AF 14mm F2.8</model> - was Samyang 14mm f/2.8 AE ED AS IF UMC
<model>SAMYANG AF 85mm F1.4</model> - was Samyang 85mm f/1.4 IF UMC Aspherical

The attached xml file contains these changes so load it into Photo's Lens Profiles Folder. Preferences\General\click button
Restart Photo

That's enough for the 14mm lens but the 85 needs a bit more help as the exif data is so mangled. Exiftool to the rescue available here https://exiftool.org/

exiftool -lens* 85.ARW
displays:

Hi @David in Яuislip;

First at all thanks for your help....

I don't found how download this file https://github.com/lensfun/lensfun/blob/master/data/db/mil-samyang.xml

I download the file that you let me at the end of the post Samyang1485.xml and i place it in "Lens Profiles Folder" as you indicate me.

This works pefect for Samyang 14mm F2.8 files now the program change the wrong 35mm for correct 14mm profile.

But with 85mm i don't understand so much what i have to do. I have to apply this command " exiftool -lenstype2#=32823 -lenstype3#=32823 *******.ARW) for each file who i want to edit??? , because i tried to edit the file Samyang1485.xml to include this :

Lens Type : E-Mount, T-Mount, Other Lens or no lens
Lens Spec : E 85mm F1.4
Lens Zoom Position : 0%
Lens Mount 2 : E-mount
Lens Type 3 : Sony FE 85mm F1.4 GM or Samyang AF 85mm F1.4
Lens E-mount Version : 1.70
Lens Firmware Version : Ver.03.002
Lens Mount : E-mount
Lens Format : Full-frame
Lens Type 2 : Sony FE 85mm F1.4 GM or Samyang AF 85mm F1.4
Lens Spec Features : E
Lens Info : 85mm f/1.4
Lens Model : SAMYANG AF 85mm F1.4
Lens ID : Samyang AF 85mm F1.4

but i can't i really donkt know how doit.

Not yet but you are half way there. Do not edit the xml file. The information you are trying to include is actually a report by Exiftool of a corrected 85mm file

Yes.

On Windows I have the Exiftool program in a folder, there is no installation prrocedure. I then set a path to that folder in the environmental variables. Then I would open the folder containing the images, open a Powershell window and do

exiftool -lenstype2#=32823 -lenstype3#=32823 *.ARW

which will process every file in that folder. I am sorry but I have no idea how to do that on a Mac but this

https://www.exiftool.org/install.html

may help. Good luck

I hope it makes sense, I am afraid that this stuff is very geeky. Another trouble is you can solve a problem one day then when you go back after a few months it's all forgotten

Joking aside, Exiftool is an astonishing achievement and the author, Phil Harvey, has made a massive contribution
