Is the sigma 28 105mm f 2 8 dg dn art worth it?

Yes, I think it's worth it if you want one lens for most everyday shooting on full frame. Staying at f/2.8 across the whole 28-105mm range is unusual, and it's bright enough for low light, portraits, and events without carrying a bag of primes. The trade-off is size and weight, and if you want really shallow backgrounds you'll still want a faster prime.

On full frame, it pairs well with the Sony a7 III, the Sony a7 IV, or the Panasonic Lumix S5 II. On APS-C, such as the Sony a6400, it frames like a roughly 42-158mm lens, which is handy for travel.

If you're still deciding whether full frame is worth the cost, read Is full frame worth it?.
