Nikon z5 ii vs panasonic lumix s1 iie?
Both are full frame mirrorless cameras announced in 2025, with stabilisation in the body. The Nikon Z5 II has 24.5 megapixels and uses the Nikon Z mount. The Panasonic Lumix S1 IIE has 24.2 megapixels and uses the L-Mount. It's the S1 II body with a simpler sensor, sold for less.
The megapixel gap is too small to matter, so I'd choose on lenses. For an everyday kit on the Nikon, the Nikon Z 24-70mm f/2.8 S and the Nikon Z 35mm f/1.8 S make a solid pair. On the Panasonic, try the Panasonic Lumix S Pro 24-70mm f/2.8 and the Panasonic Lumix S 50mm f/1.8.
If you already own Nikon or Panasonic glass, that settles it. If you don't, look at which lens range you like best.
