Nikon Z5 II vs Sigma BF

The Nikon Z5 II and the Sigma BF side by side, computed from this guide's catalogue.

Which to pick

Pick the Nikon Z5 II if you want stabilisation in the body, which steadies every lens. Pick the Sigma BF if you want a lighter body (446 g against 700 g). If you already own Nikon Z or L-Mount lenses, the camera on that mount saves you buying them again.
