Sigma Sigma Art Sigma 28-105mm f/2.8 DG DN Art Lens (L-Mount) Review

Sigma's 28-105mm F2.8 DG DN is a lens that tries to do a lot. It gives you a wide to short-telephoto zoom range with a constant bright aperture, all in one package. That's a big deal for L-mount shooters who want one lens for most situations, from landscapes to portraits.

The versatility score here is the star, sitting in the 91st percentile. That means it covers a lot of ground without you needing to swap lenses. But you're making trade-offs for that convenience. The build quality is in the bottom 6th percentile, and it lacks any image stabilization. The autofocus and optical performance are just middle-of-the-pack, and forget about close-up shots with that 17th percentile macro score.

At $1649, this lens asks a lot. You're paying for the engineering feat of a constant f/2.8 zoom over this range. But you're not getting premium build, stabilization, or close-focus ability. It's a niche tool. If that specific zoom range with that aperture is exactly what you need, it might be worth it. For most people, it's a tough sell.

This lens doesn't have a direct competitor in L-mount, which is its main advantage. But look at what you give up. A combo like the Nikon Z 35mm f/1.8 S and an 85mm prime would cost less, be sharper, have better build, and give you way better low-light performance with those wider apertures. The Viltrox 35mm f/1.7 is a fraction of the price and sharper for portraits, but you lose the zoom flexibility. This Sigma is all about that one-lens convenience, and you pay a premium for it in both cash and performance compromises.

Buy this only if you're an L-mount shooter who absolutely must have a 28-105mm f/2.8 lens and you're willing to accept average optics and no stabilization. For portrait specialists, a fast prime is a better choice. For video, the lack of stabilization is a deal-breaker. It's a solution for a very specific problem.
