Sigma BF vs Sony a7 V
The Sigma BF and the Sony a7 V side by side, computed from this guide's catalogue.
Which to pick
Pick the Sigma BF if you want a lighter body (446 g against 695 g). Pick the Sony a7 V if you want more resolution, for cropping and big prints (33 against 24.6 MP); stabilisation in the body, which steadies every lens; 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.
