Wrong built-in lens profile when using the Olympus 25mm 1.8 on X5R

Hi DJI, so here's my problem.
I use the x5r with the following lens:
Panasonic Lumix 15mm 1.7
Olympus M.Zuiko 25mm 1.8
Olympus M.Zuiko 45mm 1.8

All these normally have built-in lens profiles wich are used by Adobe Camera RAW to automatically apply lens correction to the DNG files. You can't turn this auto correction off (at least in Camera RAW).

The 15mm and 45mm are stellar, and Cinelight will export perfect dng files, even though the transfer is a little bit slow... The problem though, is with the 25mm. Somehow, the x5r applies the wrong built-in lens profile to the DNG files. So when I export these, the resulting images are plagued with an excessive amount of purple and green fringing on each side of the image. Too much to correct it with Camera RAW without impacting the overall image quality. See the screenshots attached...

It seems like the attached lens profile is the same used for the 15mm lens, this is what's causing this wrong interpretation of the image (DJI M43RAW). Now my workaround (which is NOT because it's so godamn long) is to export PRORES directly from Cinelight and by leaving unchecked "warp rectilinear". If I check it, the same fringing problem occures. It's not really a workaround because it takes days to export PRORES from Cinelight.

DJI, will you adress this flaw in an upcoming patch?!

I'm on firmware v01.08.01.40



Thanks!

When we are talking MFT lenses (Micro Four-Thirds), we are talking about lenses with built in profiles. This is done from the manufacturer, and in this case that would be Olympus.

Ever wonder why there are no lens profile corrections for MFT lenses in Lightroom or Photoshop? That's because they are built into the electronics in MFT lenses.

How do I know this? I asked Adobe quite a long time ago.

This is chromatic aberration, and its so bad that I would actually return this lens for a replacement as I have never seen an Oly 25 this bad.

This is nothing that the built in lens profile (comes from the manufacturer and its baked into the DNG as its taking pictures) would fix in this case.

Really?

But when I export TIFF, or Prores from Cinelight, the pic quality is perfect... That's what makes me dubious.

And here's what it looks like if the file is exported in Prores 4444 from Cinelight...

Hi Ed, I never got a response.
Does someone have an answer? It's keeping me from using my favourite lens on the x5r...

Bump. What is the status of this? ACR processes RAW images from the GH5 and GH4 using the same Olympus 25mm lens without any of this horribleness but when you give it a DNG from the X5R, it's bad news.
