Sigma 24 70mm f 2 8 dg dn ii art vs sony fe 24 70mm f 2 8 gm?

Both lenses are full-frame 24-70mm f/2.8 zooms with autofocus, and neither has stabilisation. On a full-frame body they frame identically, and both fit the same Sony E-mount bodies, so the choice comes down to mount and what you can find for the money.

The Sigma is the one to pick if you shoot L-Mount, since the Sony is only made for E-mount. My site doesn't compare image quality or prices, so I can't tell you which one renders better. For the constant-aperture idea behind both, see how aperture works.

If you're just starting out, a standard zoom like this is a good first lens. For the Sigma's predecessor, see Sigma 24-70mm f/2.8 DG DN Art, and for Sony's newer model, see Sony FE 24-70mm f/2.8 GM II.
