The Sigma TC-1411 1.4x Teleconverter mounts between a Leica L-Mount lens and camera body to extend focal length by a factor of 1.4. It is built for photographers who need extra reach without swapping lenses. Every unit passes Sigma's proprietary MTF measuring system A1 to verify optical quality.

Questions about this item

Which Leica L-mount lenses can the TC-1411 1.4x converter attach to?

The converter mounts between any Leica L-mount lens and an L-mount camera body, extending the focal length by 1.4x while retaining autofocus communication.

What is the correct mounting sequence for the TC-1411 converter?

How should the dust- and splash-proof seals on the TC-1411 be maintained?

Inspect the rubber gasket on the mount for debris after each use, wipe it clean with a dry cloth, and store the converter with its caps on to preserve the seal integrity.
