Sigma 1.4x Tele Converter TC-1411 for Lumix L-mount 

The SIGMA TELE CONVERTER TC-1411 is a teleconverter 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. The key to this achievement is that they are developed exclusively for mirrorless systems, and the AF is effective without being limited by the F-number.

In addition, this new teleconverter have 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 accessory 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.
