What this adapter preserves
Compatibility for Leica M lens on a Sony E body (computed from the lensmount dataset — open the Leica M to Sony E adapter page for the full verdict, flange clearance, and adapter caveats).
- Focus: Manual focus only
- IS: No IS
- Aperture: Manual aperture ring
- Infinity focus: Reaches infinity
What it does
No close-focus helicoid (unlike Voigtländer's VM-E Close Focus) — focuses to the lens's native minimum, nothing closer. For AF on M-mount glass, look at the Techart LM-EA9 instead. Tree-planting commitment per product.
Common questions
- Does the Urth Leica M to Sony E adapter close-focus past the lens's native minimum?
- No — Urth's M-to-FE adapter is a flat ring, not a helicoid. A 50 mm Summicron's native 0.7 m minimum-focus distance stays at 0.7 m through the Urth. For close-focus extension, the Voigtländer VM-E Close Focus is the canonical pick (helicoid extends flange ~4 mm, drops a 50 mm Summicron to ~0.3 m).
- Is it compatible with 6-bit coded Leica M lenses?
- Yes mechanically — the 6-bit coding on Leica M lenses is a read-only marker for Leica M bodies' onboard lens-detection. With a Sony body in the picture, the coding is ignored; the lens mounts and operates the same as any non-coded M lens. Focus, aperture, and infinity all work normally.
- How does it compare to a Novoflex SONY/LEM at 3-4× the price?
- Novoflex's German-CNC build has tighter mechanical tolerances and a dual-screw bayonet retention that virtually eliminates flange drift over years of remounting. For occasional vintage-M use Urth is fine; for daily professional use with $5000+ Summicrons or Summiluxes, Novoflex's precision is hard to argue against. Both preserve infinity focus and aperture-ring travel on the lens.
