Sigma TC-1401 1.4x Teleconverter

The Sigma TC-1401 1.4x Teleconverter multiplies the focal length of Canon mount lenses by 1.4 while still retaining full communication to enable autofocus to operate on compatible lenses at f/8.

The TC-1401 1.4x teleconverter also features one Special Low Dispersion element to reduce chromatic aberrations, and features a splash and dust proof construction for improved durability. 


Teleconverters are great for improving reach, and also increases the flange distance between the lens and body which decreases the minimum focus distance for even closer macro capabilities.

*1 It becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.01 or later.
*2 It becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.02 or later.
*3 It becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.03 or later.
*4 When SIGMA TELE CONVERTER TC-1401 is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF. In cases where contrast or brightness level of the shooting object is low, it may not focus properly.

Please be advised that the updated version of lens firmware will make it compatible with the new tele converters, however it will also make it incompatible with conventional APO TELE CONVERTER 1.4x EX DG and APO TELE CONVERTER 2x EX DG.
