These are the best L-mount lenses right now, for Panasonic's Lumix S full frame mirrorless cameras, the Leica SL and – let's not forget it – the clever little Sigma fp and fp L! The L mount is a comparatively new format, but it's backed by three big names in photography and it's gained a lot of ground in a very short time.

Growing in popularity, the L-mount is based on Leica’s T-mount system, which stems from the Leica T (Typ 701) APS-C format digital camera, launched in 2014. With the subsequent launch of the Leica SL full-frame camera, the name was changed to the L-mount, with sub-categories of TL for APS-C format lenses and SL for full-frame. Bigger news came in September 2018, with the advent of the L-mount Alliance, formed by Leica, Panasonic and Sigma. This enabled all three companies to manufacture cameras with ‘interchangeable’ lenses in every sense of the word.
