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,...
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.
Item sent back as was not compatible with my camera
Excellent service and the lens is great too
The AF doesn't work on my 150-600 C
This tele only works to 400mm on the 150-600 C lens, after that it searches and searches. goes to manual. So you Canon users be care, and Sigma said that the lens changes to F9 after 400 mm. I am sending this back and very very mad and Sigma does not care.Joe

Used the Sigma 1.4x teleconverter with the Sigma 15-600 Sport with excellent results. I saw no noticeable degradation in sharpness. Excellent combination for extra reach for wildlife photophagraphy.
works great ! sometimes autofocus struggles, but I just switch to manual focus. I've been using it with nikon d5300 and sigma 150-600 contemporary lens, making it equivalent focal lenght of 1260 mm zoomed in. I've been using it hand held in sunlight successfully.
