When mounted on compatible SIGMA lenses, the SIGMA TC-1401 Teleconverter magnifies the focal length by 1.4x. Ideal for covering extra distance without the need to carry additional telephoto lenses or when luggage weight is restricted. The use of an SLD (Special low Dispersion) glass element effectively minimises chromatic aberration to maintain optical quality.
The teleconverters dust and splash-proof design matches the weather resistant construction of SIGMA Sports lenses such as the SIGMA 150-600mm F5-6.3 DG OS HSM | Sports. The TC-1401 is also compatible with cameras that can focus at F8 when a teleconverter is attached.
