I found a Sigma EX APO DG 2X is just slightly better than a Canon 2X TCIII. Slightly sharper, slightly more contrast.

Blue-Sky Moon at Sundown. Location: Sydney, NSW Australia - Taken in JPEG - uncropped - Moon is unedited (APS-C camera)
Canon EOS-M + EF 100-400mm f/4.6-5.6L IS II USM lens + EF 2x III Extender

The Blue-Moon above was taken just as the sun was setting so there was some blue in the sky overhead. I snapped this image quickly because clouds were moving in as I was setting up to take this picture - so I didn't expect to keep this picture and it's not ideally exposed. This picture utilized just the EF 2x III Extender on the 100-400mmL lens @ 400mm. The moon image hasn't been edited or sharpened... I only had to tweak the blue tones very slightly to prevent banding when uploading.... for some reason the blue hue triggered some odd behavior when uploading to other sites. A tripod was used for each of these images. A monopod was used to support the weight of the camera in the Ibis and Lizard pictures above.
.
Now the picture below was a bit of an experiment where I used BOTH the 1.4x III and 2x III extenders together. By now the sun had truly set and the sky was black. If stacked in the following way - ( Lens + 2x + 12mm ET + 1.4x + Camera), then the camera will only identify one microprocessor in the EF Extenders and will ignore the fact that there are two Extenders mounted together. The shot below was taken with an APS-C camera (the EOS-M mirrorless camera from Canon). So the added 1.61x of the crop factor of the APS-C sensor meant the lens array added up to a rather amazing 1800mm+ focal length. The uncropped and mildly processed image can be seen below.

Half Moon. Location: Sydney, NSW Australia - Taken in JPEG - uncropped - (APS-C camera).
Canon EOS-M + EF 100-400mm f/4.6-5.6L IS II USM lens + EF 2x III Extender + Canon ETEF 12II Extension Tube + EF 1.4x III Extender

I think the Extenders serve a purpose. They are an alternative to spending obscene amounts of money when you only need to take the occasional image at higher magnifications. I think the Canon Extenders are vastly superior to the non-Canon brands when comparing the Mark III series... but they are accordingly fairly expensive. The quality of their build is superb. On my 100-400mmL II lens the Extenders still allowed use of the excellent Image Stabilizer.

Welcome to the forum! First of all, the 100-400 II is a fabulous lens. You will enjoy it very much. Second, it won't focus with the 2x extender except in Live View, and even that doesn't work very well. However, on your 7D2, you can use the 1.4x extender and get auto focusing at the center focus point. I've taken many pictures using that combination. Image quality is excellent. I think if you return the 2x extender and get the 1.4x, you'll be very satisfied.

An example (7D2 + 1.4x III + 100-400 II):
QUOTED IMAGE

Question:

I have the 100-400L and a Tamron 2x converter (used it on the 7D and currently on the 7DII), used only for shooting the moon, and in live view (where it hunts for ages before finding focus).

Now, do you know if the 1.4x converter will allow me to autofocus with the 100-400 Mk1?

Whoa! Fantastic moon shots! Great job and thanks for the detailed write up.

For myself, I'm interested in using the 100-400 II & 1.4xIII with the 1DXII for aircraft in flight photography.

That combination works well with my 1DX Mk1 so it should be fine with your 1DX Mk2.

The AF will slow a little but Aircraft will not be a challenge for it!


Life is for living, cameras are to capture it (one day I will learn how!).
