Is the sigma 50mm f 1 2 dg dn art worth it?

The Sigma 50mm f/1.2 DG DN Art is a lens for a specific job. It's a full frame prime for Sony E and L-Mount, and f/1.2 gives you a lot of light and very shallow depth of field. If you shoot people, food, or anything in dim rooms and want that soft, separated look, it's worth the money. It isn't stabilised, so you'll rely on shutter speed and your subject's movement.

If you're buying your first lens, I'd skip it. A cheap 50mm f/1.8 gets you most of the low-light and portrait benefit for far less, as I explain in your first camera. If you want a middle ground, check the Sigma 50mm f/1.4 DG DN Art. For the full-frame body that makes this lens shine, see sensor sizes.
