The SIGMA TELE CONVERTER 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 and that of TC-2001 is 2 times respectively.
Both models 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 an 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.
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, the focus may not be spot on the subject.
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.
Using the SIGMA TELE CONVERTER 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 that has a dot in the list, the camera’s display will indicate the converted exposure information.
