Sigma 17-40mm f/1.8 DC DN Art Specifications

This past week a couple of pretty impressive Sigma lenses for APS-C cameras came to light, both are fast and relatively unique in the industry. We’re going to be seeing a Sigma 17-40mm f/1.8 DC Art and a Sigma 12mm f/1.4 DC Contemporary.

Now that Sigma makes lenses for APS-C RF mount cameras, we’d be surprised if these lenses didn’t come in an RF mount variant. We haven’t seen any mount confirmations outside of the E mount for Sony Cameras

Summary

Specifications for the SIgma 12mm f/1.4 DC DN Contemporary haven’t leaked yet, but that will probably happen very soon.

We also haven’t seen any sort of pricing either, but with what we have seen from recent Sigma releases, their lenses rarely, if ever, give sticker shock.

We’re looking forward to the announcement, and we may also see a Canon announcement after June 17, 2025.
