Sigma 28 105mm f 2 8 dg dn art vs sony fe 24 105mm f 4 g oss?

Both are full-frame zooms that cover most everyday shooting, so the choice comes down to what you shoot most.

The Sigma 28-105mm f/2.8 DG DN Art is the pick for dim rooms and blurry backgrounds. f/2.8 lets in more light across the whole zoom. It also comes in L-Mount as well as Sony E, and it has no stabilisation, so you'll lean on shutter speed when handheld.

The Sony FE 24-105mm f/4 G OSS is the more practical walk-around lens. It starts wider at 24mm and has optical stabilisation, which helps with slow shutter speeds and video. It's Sony E only.

If you mostly shoot in good light, like landscapes or travel, I'd take the Sony. If you shoot people or indoors, the Sigma's extra stop is worth having. The aperture section explains why that matters.
