Sigma Teleconverter TC-1411 L-Mount

Sigma TC-1411 L-mount teleconverter

The Sigma Tele-Converter TC-1411 maintains the image quality of the lens to a high degree while extending the focal length.

Mounted between the lens and camera body, the TC-1411 increases the focal length of the camera by 1.4 times.

The teleconverter is also designed to be dust and splash-proof, comparable to the lenses in the Sports line, allowing use in harsh conditions in conjunction with dust and splash-proof camera bodies and lenses.

Tele-converters are easy to use and an affordable alternative to a larger more expensive telephoto lens, providing an "ultra-telephoto" angle of view on compatible telephoto and macro lenses while maintaining the performance of the combined lens.

Superior optical performance

Exceptional optical performance, using the latest lens design to provide a wider focal length while maintaining the performance of the combined lens.

Dust- and splash-proof design comparable to the lenses in the Sports product line

Each individual converter passes through SIGMA's proprietary "A1" MTF measurement system.
