What is L mount / L bayonet?
- L mount is developed jointly by Leica, Panasonic and Sigma, for full-frame mirrorless cameras.
- L mount cameras including: Leica SL SL2 T TL TL2 CL cameras; Panasonic Lumix S1 S1R S1H cameras; Sigma FP cameras, etc.
- L mount is not simply equivalent to Leica camera (Leica M, Leica R, Leica L are different mounts), please confirm your camera mount before purchase, or ask us for help.
Function:
- Manual adapter without electronic contacts, no auto-focus or aperture control.
- Connect M42 screw mount lens to L mount mirrorless camera.
- Support focus to infinity manually.
Aperture:
- Aperture cannot be adjusted with manual adapter, and will be defaulted to the largest.
- Aperture can only be adjusted when your lens has a manual aperture control ring itself.
- Use a zoom lens with manual adapter, set the aperture to what you want before connecting to the adapter and camera.
"Doesn't work" Problem:
- If you find the camera cannot shoot with the adapter, set your camera as "release shutter without lens" to enable when using the adapter for the first time, otherwise the camera will fail to recognize the lens and the shutter may not be released.
Note:
- L mount cameras are full-frame mirrorless cameras.
- Adapting APS-frame lens to full-frame camera may generate vignetting, which is not the problem of the adapter. Some cameras could correct it by adjusting to APSC.

Edit: they sent me a free replacementIt works to adapt a f type lens to an L mount body, but one these internal tension springs broke off after a month of use. Good thing it happened when taking a lens off, because this could destroy your sensor if it fell inside the camera.

This is better than other M42 adapter that I have tried. Very well made and well calibrated.

I'm thoroughly impressed with the K&F Concept M42 to L Mount Adapter! The build quality is fantastic – it feels sturdy and well-made, with a nice fit and finish. The adapter connects perfectly to my L-mount camera with no wobble or looseness, ensuring that my vintage lenses feel secure. I was pleasantly surprised by how smoothly it works and how easy it was to attach and detach.I'm especially excited to test this out with my Helios 44 lens, and I can’t wait to see the unique bokeh effects it’ll create on my new setup. This adapter has opened up a whole new world of possibilities for using classic M42 lenses with my modern L-mount camera. Highly recommended for anyone looking to breathe new life into their vintage lens collection!

Aucun problème, la bague s'adapte très bien sur mon s5 II et les objectifs profitent du focus peaking. Pensez à bien activer "prendre photo même sans objectif" dans le menu.Vous trouverez ce produit légèrement moins cher sur le site officiel de la marque mais attention, ils livrent depuis la Chine et leur SAV est très moyen... Passez par amazon:)

Der Adapter ist robust und präzise gefertigt. Die Montage war kinderleicht, und er sitzt fest und sicher an meinem M42 Objektiv. Es gibt keinerlei Spiel, was die Bildqualität erheblich verbessert. a der Adapter keine elektronische Verbindung zwischen Kamera und Objektiv herstellt, muss man die Belichtung manuell einstellen. Er fühlt sich hochwertig an und hat keinerlei Anzeichen von Abnutzung, obwohl ich ihn intensiv genutzt habe. Insgesamt bin ich äußerst zufrieden mit dem K&F Concept Objektivadapter M42-L. Er hat meine Erwartungen erfüllt.
