Camera Raw/Lightroom: Fuji 35mm built-in lens profile never shows the "Built-in Lens Profile applied"

Hi,

Lightroom (2015.7) does recognize and read the built-in lens profile inserted into the RAF files produced by my X-Pro1 camera for all lenses (18mm, 60mm, 18-55mm) but the 35mm. For this lens, it never shows the "Built-in Lens Profile applied" message. The firmware for the 35mm lens is up-to-date. Capture One does recognize this profile.

Any clue ?

Thanks in advance.

Can you make a screenshot of the portion of the settings that it displays please ?

Merci Régis,

I'm not sure I understand your request. I have not much to show: in the Lens Corrections | Profile tab, the "Enable Profile Corrections" option is unchecked, so everything else is grayed out and the panel should display the "Built-in Lens Profile applied" message.

Hi Patrick,

If possible will you please upload a sample image (link to DropBox or similar) and I will investigate the profile issue.

Thanks,

Interesting. First thing I notice is that with the image shot at f/2.8, the opcode for correcting vignetting (the only built-in correction for this lens as far as I know) is missing.

If I read your message above correctly, you are saying that this is the only image from that lens that is not displaying the built in profile message, yes?

It is technically possible that the camera/lens is not embedding the opcode when it detects certain apertures and/or focus positions, but this is not something ACR or Lightroom has control over.

You may wish to check with Fuji on this.

Regards,

No. The file named Dortmund_008.RAF is the only one for which LR does display the built-in profile message. For all other images I shot with this lens (used on two different cameras), the message is not displayed.

OK, I see. It still may be an issue with the camera(s) or lens firmware or an expected behavior based on Fuji's internal logic that determines when to embed the opcode. I also have this lens and access to several Fuji bodies, so I will try to reproduce it as well. I don't have the lens with me today, so it won't likely be until tomorrow that I have a chance to confirm the behavior.

Chris,

Thanks for putting me on the right track. I made further tests. It seems that the built-in profile is generated only for apertures of f/2.0 and wider. The unique photo who had a built-in profile had been inadvertently exposed at f/1.6 (which is why it is overexposed). I don't think that is is due to a lens failure. The correction for smaller apertures is probably useless.

Thanks, Patrick. 

This lens is technically very good optically, so that makes sense.
