Voigtlander VM pancake at 40mm for native Leica M mount, aspherical Heliar optics at ultra-compact 85g.
The Voigtlander Heliar 40mm f/2.8 Aspherical VM is the Leica M-mount version of the compact 40mm pancake, providing native M-mount compatibility without requiring an L39-to-M adapter. The VM mount ensures seamless integration with all Leica M bodies.
The 40mm perspective with aspherical element provides sharp images in a pancake barrel that barely extends from the M body. The native VM mount eliminates the adapter needed by the L39 version, providing a cleaner, more integrated setup on Leica M cameras.
Build quality is compact Voigtlander VM with metal construction in ultra-slim dimensions. The native M-mount bayonet provides secure, rattle-free attachment and quick lens changes that the L39 screw mount cannot match.
The VM version provides the same excellent optics as the L39 variant with the convenience of native M-mount bayonet attachment. On the used market it may command a slight premium over the L39 version for the added convenience of direct M-mount compatibility.
