Panasonic lumix g9 ii vs panasonic lumix gh7?
The G9 II and the GH7 share a sensor: 25.2 megapixels, Micro Four Thirds, with stabilisation in the body. The difference is what they're built for. The G9 II came out in 2023 and is the stills-first choice. The GH7 followed in 2024 and is a video camera first, with internal ProRes RAW and no recording limits worth worrying about.
If most of your work is photos, I'd take the G9 II. If video is the main job, get the GH7. Both take the same lenses, so for an everyday kit I'd start with the Panasonic Leica DG 12-35mm f/2.8 for general zoom work, the Olympus M.Zuiko 40-150mm f/2.8 PRO for reach, and the Panasonic Leica DG 25mm f/1.4 II for low light. On this system those frame like roughly 24-70mm, 80-300mm and 50mm on full frame.
