Thanks Sirius!
"Shoot more film" is in my case probably simply "shoot more". When picking up my Df I looked at the pictures which were still on the camera's memory card. Apart from a couple dozen test pics of my freshly acquired Voigtlander 40mm in summer 2022, the last time I used it was 2021...
As for this weekend's trip, until now I wanted to shoot digital for convenience and sharing the pics with my friend; but you are right I could take my F6 instead. My freezer is still full of 35mm rolls!!
