The Panasonic Lumix S9 is a miniature S5II, designed for travel and social media shooting.
This is a Panasonic-made USB-PD powered DC coupler (aka dummy battery) for most LUMIX cameras made since the GH3. Other than providing continuous power to your camera, on the GH7 it will enable recording high frame rate 4K video (4K120) to an external SSD.
This is the Laowa 10mm f/2.8 full frame lens, available in LUMIX L-Mount, Canon RF, Sony FE and Nikon Z. This lens is wide. You just won't believe how vastly, hugely, mind-bogglingly wide it is. I mean, you may think your 18mm is wide, but that's just peanuts to this lens.
The LUMIX S9 is a compact, lightweight, full frame camera with updated realtime LUT, Hybrid Zoom, and is accompanied by the new LUMIX Lab mobile app.
