Two new L-mount lenses in the Sigma lineup are announced today. Both are in the Contemporary range and have been designed from scratch for mirrorless cameras, including L-mount and Sony E-mount.
The duo joins four existing Contemporary primes, the 24mm f/3.5, the 45mm f/2.8, the 35mm f/2 and the 60mm f/2. All bear the distinctive styling of the original 45mm f/2.8 which was designed to complement the Sigma fp camera at launch.
The six Contemporary primes offer an inexpensive but high-quality option for owners of both Leica and Panasonic L-mount cameras.

The new 24 mm f/2 DG DN and the 90mm f/2.8 both retail at a competitive £549.99, including tax and will be available from authorised retailers from 24 September.
Since the launch of the L-mount Alliance in the autumn of 2018, the range of compatible lenses has grown far faster than industry watchers had anticipated. Both Panasonic and Leica have contributed new lenses, but Sigma has been the centre of most activities.

These 2 Sigmas add to what is now becoming my go-to option for SL primes. When I bought my SL2-s (bundled with the Vario Elmarit 24-70 & L-M adapter – a good deal in Leica Land) my plan was to simply add the 45mm f2.8 Sigma, which I duly did; and to use my adapted M-Summarit 75 to get my ‘M-fix’.
BUT! These lovely Sigma I-series are giving me real problems and I’m definitely going to add this new 24mm f2. M-lenses, obviously, adapt beautifully to SL cameras but it’s as if this range of Sigma Contemporary lenses are aimed at providing us with an M-like autofocus alternative: solid, compact, with aperture rings, tactile, optically excellent. And, great value for money. Wow!
Between this Sigma 24mm (on the fpL) and the Ricoh GR IIIx I’m in heaven today!
The 21 mm and 24mm were announced in September 2018 to be precise… 3 years ago… Leica is aggressively and increasingly marketing M glass on the SL2(s)… I sincerely wonder whether there is going to be much more Leica-branded L glass after the 21mm and the 24mm have been released…
I agree!
Especially since there have been no new announcements of SL glass for 3 to 4 years from now as they did originally. My Leica SL glass roadmap is quite yellowed with age. If it was not for Sigma and Panasonic, L mount (aps-c or full frame) would be as dead as the Hasselblad X1D system. I exited the Hasselblad X1D sytem and went back to Leica SL2 system when panasonic and sigma offered options. Leica seems to put all their energy into M special editions and the occasional new M lens. In contrast, voigtlander is cranking out amazing glass at a fraction of the price.
The Leica SL2 is the best camera I have ever used. So I am delighted that it has a great photography shooting envelope due to Panasonic and Sigma. I realize it is not the best for sports but for me it is the best for my photography.
My X1D II is not going anywhere. It replaced my Leica gear for travel and is increasingly being used in other areas as well. Lens options are always going to be limited but they already have more lenses than the Leica S system (which unfortunately is truly as dead as dead can be…). About the M glass, Leica can sell it at a higher price and they sell much more of it. It makes business sense but I am not sure where that leaves the L mount…
The X1D camera has the best image files and their colour science is amazing. It also has the best camera haptics of any camera. However, the electronic shutter readout was too slow for my m glass so I moved back to the SL2 which is the second best camera to use with m glass. I agree with you that the Leica S system is dead; very dead and not to mention seriously over priced for a dead system.
Great news! Panasonic and Sigma are delivering glass I and others want – and keeping L mount alive. We can pick and choose: big and heavy or reasonably small, cherry pick among Leica, Panasonic and Sigma.
Are the Leica SL wide angles coming – they were announced years ago for 2020 and then moved to 2021. I do realize the SL 28 finally arrived. But I wanted the 24mm. The Leica SL glass is very limited.
