When you buy an interchangeable-lens camera, you also buy into a lens system. For many, that means optics from the same manufacturer as your camera, with some third-party supplements. The L-Mount mirrorless system is a bit different—although Leica started it by itself, Panasonic and Sigma are both full partners. Together, the three make up the L-Mount Alliance.
This brand diversity has already delivered some niche cameras that you won't find for other systems. The Leica SL2 is pure German engineering, with stunning industrial design to match, while the Sigma fp is the absolute smallest full-frame mirrorless camera out there. Panasonic covers the mainstream with the crowd-pleasing S5 and S5 II, while video pros can look to the S1H to record at 6K quality.
You also get access to three lens design philosophies. Leica concentrates on premium primes, Sigma's wares run the gamut from value to exotic options that open to F1.2, and Panasonic focuses on more traditional entries. All the basics are available, and you can mix and match glass to your heart's content.
We're here to break down the best lenses available for the system. Most are full-frame and made specifically for this mirrorless platform, but we also included several APS-C options and a few of Sigma's older SLR designs in separate sections.
The Panasonic Lumix S 20-60mm F3.5-5.6's wider-than-normal coverage, coupled with quality construction, makes it the best starter lens for any full-frame camera system.
