The Sigma Teleconverter is developed exclusively for the new lens lines. By mounting it in between a telephoto lens and a camera, the offered magnification of focal length of TC-1401 is 1.4 times. This Tele Converter lens incorporates 1 SLD (Special Low Dispersion) glass element that offers excellent aberration correction. It is exceptional for a lens accessory to use one of the best glass materials, yet this is because Sigma is seeking for the best image quality, and it is necessary to meet the SGV standards. It is suitable for professional use since its durable construction is dust and splash-proof. It is compact and light, and provides easy extension of focal range. SLD Glass Elements The TC-1401 incorporates 1 SLD (Special Low Dispersion) glass element. By minimizing chromatic aberration effectively, it has achieved very good optical performance, thus it is possible to maintain the optical quality of the original lens. Compatible with Large Diameter Lenses Its power distribution is designed for lenses of large diameter. Without affecting the lens performance, it offers stable image quality until corners. The rich peripheral brightness enables shooting quality images at every focal length. Dust and Splash-Proof Construction It is dust and splash-proof, and designed for higher durability. Sigma 150-600mm f/5-6.3 GD OS HSM Sports and other telephoto lenses are able to meet the demands that professional photographers would require in severe shooting conditions, such as in the rain. AF is Effective up to f/8 When the new Sigma Tele Converter is attached to cameras that are compatible with AF at f/8, it is possible to shoot with AF. Ease of Use A rubber part is attached to where it mounts with the original lens, and it prevents the devices from scratching each other. It has the same materials and finishing for integrated design as the lenses from the new product lines.
