Best L-Mount Lenses for Leica SL, Lumix S and Sigma fp Cameras

In October 2015, Leica introduced the professional Leica SL as its first mirrorless interchangeable lens camera with a full-frame sensor and an L-mount. The L-mount was so far limited to Leica products, but things took a surprising turn in September 2018 when Leica, Panasonic and Sigma announced the L-Mount Alliance. It allows  all three partners to use the L-mount not only for their lenses, but also for their cameras. The Panasonic Lumix S1 and the high-resolution S1R cameras were introduced in February 2019, followed by the 6K video-centric Lumix S1H in May 2019, the compact Sigma fp in July 2019, the high-resolution Leica SL2 in November 2019, the entry-level Lumix S5 in September 2020, the hybrid Leica SL2-S in December 2020 and the studio video camera Lumix BS1H in October 2021.

This page provides an overview of the quickly growing catalog of full-frame L-mount lenses. These are mostly autofocus lenses, but selected manual focus lenses may also be included. APS-C L-mount lenses for cameras with smaller sensors are listed separately.

For every lens, the following major characteristics are given:

  • Focal length.
  • Maximum aperture. It has a strong influence on the lighting conditions under which the lens can be used, and how shallow the depth of field can be. Fast lenses also tend to be much more expensive. Green labels indicate fast lenses (> f/2), red labels indicate slow lenses (< f/4).
  • Filter size. It serves as a representative of the length, diameter and weight of the lens. Green labels indicate compact lenses (filter size < 60 mm), red labels indicate big lenses (> 70 mm).
  • Minimum focus distance (MFD). It has a major influence on the magnification that can be achieved, as well as the depth of field.
  • Another important point is of course the price, but it is different in every market and currency. Instead, links to independent reviews are given which will help you to find the best lens for your needs.

Note that additional designations such as ASPH, OIS and OS that are not necessary to identify a lens are omitted. Manual focus lenses are marked by an asterisk (*), manual focus lenses with no digital coupling to the camera are marked by a double asterisk (**).
