Teleconverters designed exclusively
for L-Mount lenses
The SIGMA TELE CONVERTER TC-2011 is designed exclusively for the use with SIGMA L-Mount lenses. Mounted between a lens and a camera body, the TC-2011 magnifies the focal length of the camera by 2x
The superior optical performance of the SIGMA Contemporary, Art and Sports lines of lenses is the result of efforts to pursue the highest levels of image quality. The SIGMA TELE CONVERTER TC-2011 upholds the image quality of the original lens to the utmost, while extending the focal length.
In addition, this new teleconverter has a dust- and splash-proof construction comparable to that of the Sports line lenses, and can withstand harsh outdoor shooting environments when combined with a dust- and splash-proof camera body and lens.
This lightweight and compact accessorie is capable of single-handedly, providing an “ultra telephoto” angle of view for telephoto and macro lenses, while upgrading the performance of the original lenses; the SIGMA TELE CONVERTER TC-2011 will be a new special gear for users.

Every single converter undergoes SIGMA’s proprietary MTF measuring system “A1”
We used to measure lens performance with an MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA TELE CONVERTER TC-2011 will all be checked using this “A1” before they are shipped.
