Attaching the Leica (L39) Screw-Mount Lenses to the M body
The L-M Ring is ideal when the thickness is 1.00 mm with high precision.(1.00 mm = Flange back difference of the Leica Screw-Mount and M-Mount)
Thickness error will influence the interlocking precision of the rangefinder.
The accuracy of the distance scale will be influenced by two-stage mounting on a mirrorless camera other than Leica.
RAYQUAL L-M Rings are manufactured with a high thickness precision of 1.00 mm, allowing for shooting that takes advantage of rangefinders and distance scales.
Furthermore, manufactured so that they can be attached and detached to the lens and camera body with a feel close to that of the genuine combination.
