The first thing you notice about the Sigma 10-18mm f/2.8 DC DN Contemporary is just how compact and adorable it is. In fact, Sigma claims that it is the smallest and lightest ultra-wide APS-C zoom lens on the market. Having used it myself, I wouldn’t disagree with that statement.
Sigma has announced the 18-50mm f/2.8 DC DN Contemporary lens which it bills as the smallest and lightest f/2.8 zoom lens for APS-C format mirrorless cameras on the market.
Sigma has expanded its series of primes categorized under its I-series line with the 90mm f/2.8 DG DN and the 24mm f/2 DG DN lenses. Both will be available in Sony E-mount and Leica L-mount.
The Sigma 28-70mm f/2.8 DG DN is a compacted take on the popular "desert island" 24-70mm f/2.8 lens that makes a slight concession in focal range at the wide end in order to make itself smaller, lighter, and cheaper: just $900.
Sigma has announced the 28-70mm f/2.8 DG DN zoom lens for Sony E-Mount and L-Mount. In contrast to what is commonly associated with Sigma lenses, the company says this new lens is the smallest and lightest full-frame f/2.8 standard zoom for mirrorless systems currently available.
When Sigma calls their new Contemporary 100-400mm f/5-6.3 DG OS HSM a "light bazooka," we're not sure which definition of "light" they're using. But given the lens' f/5 max aperture and ultra-light construction, we're going to guess they mean light as in lightweight.
