Following the launch of the L-Mount alliance, Panasonic has revealed a pair of full-frame L-Mount mirrorless cameras, the 47-megapixel Lumix S1R and 24-megapixel S1. Both have built-in image stabilization, a large, high-resolution EVF, triaxial tilt LCD for both selfie photographers and vloggers, the highest flash sync speeds on the market, and double slots for SD and XQD cards. Both models are set to arrive in spring of 2019, with further specifications to be revealed later.
To take on its larger rivals, Panasonic isn't going it alone. It has partnered with Sigma and Leica, and will be using Leica's existing full-frame-L mount system. That's a practical move, as Panasonic and Leica have worked together in the past, and Leica already has nearly a dozen SL lenses and adapters. The mount is compatible with its APS-C TL lenses, too.
