Both models (TC1401 1.4x & TC2001 2x) incorporate SLD (Special Low Dispersion) glass elements that offer 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 new "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.


Incorporating SLD glass elements for better image quality

TC-1401 incorporates 1 SLD (Special Low Dispersion) glass element, and TC-2001 carries 2. 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 lenses of large diameter

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.


The durable dust and splash-proof construction is suitable for professional use

It is dust and splash-proof, and designed for higher durability. SIGMA 150-600mm F5-6.3 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 F8

When the new SIGMA TELE CONVERTER is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF.

* When shooting subjects with low contrast or luminosity value, focus may not be spot on the subject.


Evaluation with SIGMA's own MTF measuring system "A1"

We used to measure lens performance with an MTF measuring system using conventional sensors. However, we've now developed our 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-1401 and TC-2001 will all be checked using this "A1" before they are shipped.


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.


"Made in Japan" with the best craftsmanship

All Sigma's manufacturing - right down to the molds and parts - is carried out under an integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely "made in Japan".

Using the APO Tele Converter EX decreases the effective aperture by one F-stop (with 1.4x Tele Converter) or by two F-stops (with 2x Tele Converter).Regardless of exposure mode, correct exposure can be obtained. If using a lens which has in the list, the camera's display will indicate the converted exposure information.



On the lists, the lenses marked "AF" will retain auto focus operation when used with a Tele Converter. The lenses marked "MF can only be used for manual focus. Some lenses will be operated AF even mentioned "MF", however, be aware that these lenses cannot focus precisely by auto focusing.
