Question about raw file format on K1 M2

I set up raw file to be DNG. However when I use B shutter (Bulb), If exposure time is longer than 30 seconds, photo is PEF. If exposure time is less than 30 seconds, photo is DNG. This is really weird. I do not know where I can change it, keep the file always to be DNG. Any suggestion?

Thank you.

Do you use saved User modes? If so, the PEF setting may have been included in one of those.

Hi fellow Pentaxian,

I am not a K1 user so I know very little about that camera, just a thought you may want to check out page 48 of your user manual.

Also as a second thought have you updated the firmware? New update on June 18/2020. Latest PENTAX K-1 Mark II Firmware Update : Software Downloads | RICOH IMAGING

if you load or have version 1.05 it includes all of 1.03 and 1.04

make sure you have a fully charged battery

and use slot 1 for the upgrade sd card

Thanks for your all answers. I checked camera again. Did test. I found out it was setting problem. I set up DNG for raw but this is working for all modes except B shutter mode. Under B mode I have to go to the menu and set up raw file again. It was PEF. I do not understand why I need to set it up twice but problem is solved.

Thanks for all suggestions.
