Full Details


The TC-2001 incorporates 1 SLD (Special Low Dispersion) glass element.

By minimising chromatic aberration effectively it has achieved very good optical performance, maintaining the optical quality of the original lens.


Its power distribution is designed for lenses of large diameter. Stable image quality is achieved right to the corners. The rich peripheral brightness enables images to be captured at every focal length.


The TC-2001 is dust and splash-proof, designed for higher durability. Lenses such as the SIGMA 150-600mm F5-6.3 GD OS HSM | Sports and other telephoto lenses can be used in rain.


It is possible to shoot with AF with lenses supporting AF up to f/8. Evaluation with SIGMA's own MTF measuring system "A1". SIGMA has developed their own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA TELE CONVERTER TC-2001 will all be checked using this "A1" before they are shipped.


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.
