I am a Sony a7iii user shooting raw. I read Clee01l's January 8, 2015 discussion on DNG vs NEF. Does the same logic apply to Sony's AWR vs DNG, Cletus? To all, what logic do you suggest I use in deciding between Copy and Copy as DNG when AWR is coming out of the camera?
Thanks for the help.

Since you did not provide a link to my 2015 discussion, I’ll have to “wing it” Although I don’t think my position on DNG has changed a lot over time.
When I had a Pentax, it was capable of writing DNG in the camera or Pentax proprietary RAW format. I chose DNG in the camera and did not need to convert. When I switched to Nikon, I did not consider DNG as important.
Camera Manufacturers are able to put proprietary data in to proprietary RAW formats that MAY be useful when future technology is available to handle it (think for example being able to mathematically correct out of focus data recorded by the camera).

While converting to DNG does preserve this mfg collected data, it does not allow mfg future technology to use that data. The proprietary RAW format preserves any mfg proprietary data for future technology. This holds true for Nikon Sony or any other mfg that has proprietary RAW formats and special mfg data.

Quite simply ask yourself what actual benefit do you get (now) from converting?

Fair question. This Blog listed some Pros and Cons:


The answer won't be the same for everyone!

Thanks for the article posting Paul. I've recently become aware of the lack of support for MAKER NOTES in Adobe. I was not aware of it for DNG. Wonder if it's related.

Maker’s notes is defined in EXIF as one large user structured field. Each “maker” (Manufacturer) will structure the field differently and the Makers Notes field is variable in length. Adobe ignores this field since it can container different elements for different manufacturers. But it does preserve it as a pass through. The DNG format does also preserve it as a pass through. There is no data contained inside that can be used to enhance the Adobe processing and therefore it is universally ignored for all manufacturers when converting RAW data to RGB.

Actually, I've found the MAKER NOTES to disappear on exporting from LR.
What I was referencing is that by converting to DNG, Adobe preserves the Makers notes section of EXIF. OF the RAW DNG. And this metadata would be maintained in the Lightroom Catalog. Exporting is different. I don’t believe there is a Makers note section in the JPEG header structure. There is no reason to expect Makers notes to show up in the Exported JPEG. You can check the in camera JPEG and you won’t find the Makers Notes there either.
