I use this on the 150-600mm Contemporary lens which I mainly use on my EOS C100 video camera. Surprisingly enough(!) the C100 Dual Pixel autofocus works reasonably well even with the 2001 installed.

I've tried a couple solutions to getting better reach with my DSLR over the past two decades. As time goes on it seems I throw more and more money and the desire to create deep compression and get background separation for a given subject - usually birds but sometimes elements within a landscape and...

So this teleconverter is well built as we all have come to expect from sigma. I am using it on a sigma 150-600 contemporary (great lens). Unfortunately this lens is not super fast and not even a constant aperture. This is then made even worse when you put the teleconverter on.

Paired with the Sigma 100-600 lens it’s amazing! Better than expected! Sometimes it misses focus and hunts around but it’s nothing I can’t deal with. Photo posted below is shot with a Nikon d850 sigma 100-600 contemporary lens camera in DX format for extra reach paired with the 2x teleconverter.

I used this with my Sigma 150-600 Sport lens to shoot the eclipse, and got great, sharp shots. Autofocus doesn't work with this teleconverter, which limits its usefulness. Extends my lens out to 1200mm, 1920mm on my 7DmkII

I purchased this to attach to the Sigma 150-600 Sports - mainly to take pictures of the Solar Eclipse. However, try as I may could not get good focus using it. I knew it can't be the lens because I shot the eclipse and totality without the teleconverter and my images are tack sharp.

It is an amazing piece, although a little hard to attach, it's a great assessory.

I tried this converter many times and quickly realized how difficult it is to focus manually with a combination with my Sigma 150-600 mm Contemporary lens. The lens itself does a very good job. AF works nice, but with TC-2001 you have to focus only manually.

As a rule, I have never found 2X tele extenders to meet my expectations with regard to resolution. I am happy to report that this one surprised me. I use it both on my Canon 6D and EOS 5M along with my Sigma 150-600 Contemporary.
