Teleconverters Designed Exclusively for L-Mount Lenses

The SIGMA TELE CONVERTER TC-1411 are teleconverters designed exclusively for the use with SIGMA L-Mount lenses. Mounted between a lens and a camera body, the TC-1411 magnifies the focal length of the camera by 1.4x.
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-1411 upholds the image quality of the original lens to the utmost, while extending the focal length.
In addition, the new teleconverters have a dust- and splash-resistant construction comparable to that of the Sports line lenses, and can withstand harsh outdoor shooting environments when combined with a dust- and splash-resistant camera body and lens.
These lightweight and compact accessories are 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-1411 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-1411 will all be checked using this "A1" before they are shipped.

"Made in Japan" Craftsmanship

All SIGMA's manufacturing – right down to the molds and parts – is carried out under an integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely "made in Japan". We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.
