What format do you use to shoot with your S camera?

Dng and jpg, which one do you use more?

Then I found that the quality of jpg is also very good (of course dng has more room for post-production)

never use jpg, in any camera

DNG only. The main reason to use JPEG in the S for me was only if I wanted to shoot in black and white, and switching to B&W jpeg would make the previews B&W (at least I believe it did...it was not something I did much).

Personally I do not see much reason to shoot jpeg. Jpegs can easily be produced as required from Lightroom in batch or one by one. I do shoot DNG plus jpeg in the Ricoh GR as it is a pocket camera and has some interesting B&W modes (hard bw), but for anything serious I would go back to the DNG and process it.

DNG only, export JPEgs as needed and never at full resolution.

Both. It only costs memory space, but JPG gives one more reference look.

Agreed, DNG only.   JPG’s can be exported, and it seems wasteful to take a JPG that I will only delete, guaranteed.
