Special Features

1. 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 excellent optical performance, thus it is possible to maintain the optical quality of the original lens. 

2. 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 even to the corners. The rich peripheral brightness enables shooting quality images at every focal length. 

3. 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 DG 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. 

4. 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.

5. 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.

Well constructed, easy to fit to camera and lens.
Under various lighting conditions outside, I found auto focus searching even for still objects. In dull or overcast conditions performance was poor.

My camera/TC was fixed solid to a hide shelf using a bench clamp, so there was no unwanted movement or camera shake that could be blamed for lack of expected performance.

I bought the TC to give me more reach for bird photography. However flight shots were out of the question because the lens could not lock on the target and continually searched for the subject.

Very disappointed given that this TC was designed specifically for the Sigma Contemporary 150-600 lens. I feel the only use for me would be in my photographing still birds in bright sunshine, however I would need a more versatile TC to be of use under any conditions.
