Thanks for posting this. I downloaded most of the raw files. They are really quite good, among the best I've seen. i'd say Leica knows how to make a very good camera for photography.
(You know me) I also processed them with Lightroom HDR, viewing on a Pro Display XDR - to get a feel for the 15 stops of dynamic range. This really brought out the colors, the highlights and the shadow detail. The bright chrome on the antique automobiles pulls them into the present from their ancien past. Photo 32.dng, with its old pipes and valves and lighting from below becomes a masterpiece. The model's metallic dress brings her alive, you can see why she chose it and wore it. The SL3 is an HDR making machine.
I looked at the videos, color grading them with DaVinci Resolve. Ho hum, the person shooting the video has no feel for this, and it is so bad it is hard to look at and takes away from the color, lights, and dynamic range. It is sad, the person who shot the photographs was obviously very talented while the person that shot the videos had no clue. And the camera had trouble holding focus from time to time; but I'm guessing that wasn't the camers's fault. I really don't know whether the SL3 is a good video camera or not. The nice thing is my MacBook Pro handled both the 8K 30p and the 4K 60p just fine.
Would I buy this camera? I'm very much a hybrid shooter, so I want excellence in both photography and video. No doubt the photography is there. The video, probably not.
