The SIGMA TC-2011 teleconverter exclusively for SIGMA L-Mount lenses connects between a compatible lens and camera body to magnify the focal length of the lens by 2x. When paired with long telephoto lenses such as the SIGMA 60-600mm F4.5-6.3 DG DN OS | Sports the focal length is increased to an impressive 1200mm. Weighing only 205g, the TC-2011 is a versatile photographic tool perfect for sport, wildlife and action photographers looking to increase focal length with compromising on image quality and weight.
The teleconverter has a splash and dust-proof construction comparable to SIGMA Sports lenses allowing photographers to shoot in all types of weather. The optical construction of the teleconverter is able to retain the optical quality of the attached lens, with sharp results through the full focal length. Auto focus is also possible and is effective at all apertures and focal lengths.
