The Sigma TC-1401 incorporates SLD (Special Low Dispersion) glass elements that offer excellent aberration correction. It is unusual 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.

- Compatible with lenses of large diameter
- Durable dust and splash-proof construction is suitable for professional use
- AF is effective up to F8
- Evaluation with Sigma's own MTF measuring system “A1”
Incorporating SLD glass elements for better image quality
TC-1401 incorporates 1 SLD (Special Low Dispersion) glass element. By minimizing chromatic aberration effectively, it has achieved excellent 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 even to the 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 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.
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.
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.
I would recommend it. I used it over the weekend on my sigma 150-600 whilst I was photographing wild red deer.
updated comments: The bare 150-600mm lens alone is good but the combo of the lens and the teleconvereter has AF focal problem. Even so I did the maximum AF microadjustment both at the lens and my Canon 5D4, there still is serious back focus problem at 840mm focal length and long distance.
I use this teleconverter with my Sigma 150-600mm C lens. I don't notice much if any loss in image quality when using this teleconverter. It is made very well and feels very solid when you hold it in your hand. My D800 can auto focus at 840mm (600mm as marked on the lens) about half the time.
Using this with a Sigma 500 F4 and it is great. Optically I see zero degradation of image quality. Better than I expected in every way. Not sure how it will behave on a slower lens (i.e - 150-600 zoom) since autofocus will come into play with many camera bodies.
Gives me the extra reach I needed for wildlife shots. The autofocus works at f8 and higher with good clarity on my Sigma 150-600mm. I highly recommend it.
I purchased this TC to go with my Sigma 150-600mm Sport. The D810 will auto focus between f/7.1 and f/9, depending on which focal length the lens is set at. I've had it out a couple of time so far, IMHO, image quality is very good to excellent.
I have two cameras that I have used it on. With the Canon 7d mark 2 the focusing is so slow and not very accurate. With my Canon 5d mark 4 the focusing is faster. The images are just barely acceptable.
