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 camera with an L-mount and a full frame sensor. 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 for their cameras and lenses. The Panasonic Lumix S1 and S1R cameras were introduced in February 2019, followed by the 6K video capable Lumix S1H in May 2019, the compact Sigma fp in July 2019 and the second generation Leica SL2 in November 2019.

This page provides an overview of the growing catalog of L-mount full frame lenses. These are mostly autofocus lenses, but selected manual focus lenses may also be included. APS-C lenses which are not suitable for full frame cameras are listed separately.

For every lens, the following major characteristics are given:

  • Focal length.
  • Maximum aperture. It has a strong influence on the light conditions in 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 interesting point is of course the price, but it is different in every market and currency. Instead, links to independent reviews are given.
