Great TC from Sigma.. Like other brands it does not work with ALL lenses, but I have used it successfully with Canon lenses as well as Sigma. Excellent resolution is maintained.

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.

Recently purchased this 1.4x Sigma converter having a blast with it so far it's working very well for me

Tend to use this with a sigma 150-600mm sport lens and really pleased with the quality of the images I get with this combination especially after a bit of fine tuning using the USB dock.

I recently purchased this Sigma TC-1401 1.4x Teleconverter to replace the early not so well made version. After using its predecessor with limited use for around three years, it blooming started to come apart!

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.

i shoot with a canon 1dx. i bought this to use with my sigma 150-600 sport lens, which i love. the sport by itself focuses fine, with all focusing points active. but when i use it with the teleconverter, i can only use the center focusing point, all other points disappear.

So far, so good. Much better IQ than I would have expected with a teleconverter. Using this with the Sigma 150-600mm Sport.
