Sigma fp vs Sony FX3
The Sigma fp and the Sony FX3 side by side, computed from this guide's catalogue.
Which to pick
Pick the Sigma fp if you want more resolution, for cropping and big prints (24.6 against 12.1 MP) and a lighter body (422 g against 715 g). Pick the Sony FX3 if you want stabilisation in the body, which steadies every lens; a newer model (2021 against 2019), which usually means better autofocus and video; and more lenses made for it in this guide (278 against 158). If you already own L-Mount or Sony E lenses, the camera on that mount saves you buying them again.
