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 love this thing. The images are sharp and except for the extra reach I don't even notice it. The biggest surprise for me was that it auto focuses at all apertures. I had read that f8 was the limit so I expected that using the big lens would mean shooting wide open if I wanted to use auto focus,...

Seems to work with my Nikon D810 and both my Sigma 150-600mm and Sigma 100-400mm lens. I'm still learning how to set the functions so the pictures are not dark. But most of my photos are excellent with the converter. Takes some figuring it out.

A much improved version from the apo version obviously what ever yo stick in front of the sensor will reduce sharpness quality but would recommend the 1401

I am using this converter with a Nikon D7200 SLR camera and a Sigma 150 to 600 mm C lens. Its very well made and fits the Nikon body and Sigma lens perfectly. I have been testing its performance . The Nikon 7200 now Auto focuses at F9 and at maximum zoom you get an equivalent of 840mm.

Have already sent it back once as it stopped working. It's now stopped again.

Bought this specifically to use with Sigma's 100-400 C and my trusty Canon 6D. The lens alone works like a charm but with the TC-1401 the AF refuses to function, no matter what settings are used on camera and/or lens combo.

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.
