SIGMA TC-2011 2x Teleconverter for Leica L Mount

SKU CH-8KRX-V0VDW

A 2x teleconverter for Leica L Mount lenses that doubles focal length while maintaining optical quality and adding dust- and splash-proof construction

  • Doubles focal length with 2x magnification
  • Maintains original lens image quality through precision optics
  • Withstands harsh weather with dust- and splash-proof construction
  • Supports autofocus for fast, accurate focusing
  • Each unit verified by SIGMA proprietary MTF A1 system

Purpose-built for L-Mount systems

The Sigma TC-2011 2x Teleconverter is designed exclusively for Sigma L-Mount lenses. Mounted between the lens and camera body, it doubles the focal length while preserving the optical quality of Contemporary, Art and Sports line optics. It suits photographers who need extra reach without carrying a longer lens.

Consistent magnification under continuous use

The converter maintains its 2x magnification factor throughout extended shooting sessions. Autofocus compatibility remains active, allowing the camera to track subjects as the effective focal length increases. Every unit passes Sigma’s proprietary MTF measuring system A1, confirming that resolution and contrast hold steady across the frame during prolonged operation.

Sealed construction for harsh environments

A dust- and splash-proof build matches the protection level of Sigma Sports line lenses. When paired with a similarly sealed camera and lens, the combination resists moisture and particulates during outdoor work. The lightweight, compact design adds minimal bulk, keeping the overall kit manageable for handheld telephoto and macro applications.
