Sigma 28 105mm f 2 8 dg dn art vs tamron 35 150mm f 2 2 8 di iii vxd?

Both are full frame zooms, and they split on what you want from them.

The Sigma 28-105mm f/2.8 DG DN Art holds f/2.8 across its whole range and starts wider at 28mm, so it suits everyday walkaround and general shooting. It mounts on Sony E and L-Mount.

The Tamron 35-150mm f/2-2.8 Di III VXD reaches further, to 150mm, and opens to f/2 at 35mm, though it drops to f/2.8 as you zoom in. That makes it my pick for portraits and events where you want reach and extra background blur at the short end. It mounts on Sony E and Nikon Z.

Neither is stabilised. If you're on Sony E and want steady f/2.8 with a wider start, take the Sigma. If you want more reach and a brighter wide end, take the Tamron. For how aperture changes background blur on smaller sensors, see the focal length converter.
