It would be awesome to see a firmware update that brought the ability to take DNG photos with the Spark!

Yes it would. There's been numerous threads on here asking for it and no positive response from any of the DJI folks, so I doubt we'll see it anytime soon if ever.

This issue has been discussed here dozens times. The DJI answer is that they have no plans to add raw support in Spark. Personally I suspect that this is purely a marketing decision to differentiate more Spark and Mavic.
I would also like to have a raw support but we will not see it anytime soon.

If they launch a spark 2 with dng , eventually they will enable dng in spark one....Yes i know....It is called marketing...

I agree - RAW stills would be nice like on the Mavic.

Was there any indication this might happen?
