I forgot to say: What makes this decision even more difficult is the possibility of Canon releasing the rumoured 200-600 in the near future, which I think would be the lens for me. If it came out after I made this move, I'd be frosted.

I had the Canon 100-400 II with the 1.4x III at the same time as the Sigma 150-600 C for Canon

Using Reikan Focal Pro on the 7DII, they were both just as sharp wide open at 400 mm and wide open at 560/ 600 mm. Their curves were pretty similar as I stopped down too.

I still have the Sigma 150-600 C for my Nikon D5500. I just bought a Sigma 100-400 and a Canon 100-400 II to use on my D80 and Panasonic G85. I will probably buy another Canon 1.4x III to use on both lensesides, instead of the Sigma 1.4x (unless someone has tested both and can advise? )

I am going to Florida at the end of November. I probably won't have time to test and compare the lenses until mid-December though, I have some Irma repairs that needs to get done first.

Given the relative size, weight, and price , I can see making a case to keep both lenses, especially for use on the Panasonic, unless the Sigma is as good as the Canon. TBD of course.

I am struggling with giving up on Nikon, but the synergy of using Canon lenses on both the Canon and Panasonic keeps pulling me back to Canon. (Although another D810 could be a pretty tempting impulse buy.) But 3 systems, and duplicate parts of 3 lens kits- a duplicate 17-50, 70-200 and similar, has been driving me a bit crazy for years.☺

I did some testing between the Canon 100-400 II and Tamron 150-600 G2 this afternoon, with the 5DIV and 7DII. While I kept my tripod in one location and shot at a single, vertical perch (with lots of visiting small birds), it wasn’t ideal as the light was changing quite a bit, and the light was generally on the poor side, requiring ~1600 ISO.

So, while this little exercise was by no means scientific, it did reveal that the Canon lens does outperform the Tamron. Not by much mind you, it was close. There’s just that “certain sharpness” with the

100-400II with 2xTCIII is at f/11 so Canon won't even attempt focus. But I tried it yesterday and it does work in LV (and manually)

Yes, I manually focused with it for a few test shots. Need better light.

I had to send my Tam G2 in for warranty work on the VC. In the meantime I rented a 100-400 II. There was no question for me after using both. I got the G2 back working fine, but I sold it and bought the Canon. I was using a 70D at the time.

The Tamron is fine lens, but that extra 200 mm comes at a cost. It is significantly larger. I also have the Canon 1.4x, but I rarely use it. It definitely hinders af on my 5Ds, but the images are sharp. 400mm is usually good enough for my uses, and the 5Ds has the same pixel density as the 70D.

Thanks for sharing your experience. For me, the 400 with 1.4x will barely be enough; it seems I'm almost always at the long end for birds, unless I'm sitting in a blind in the back yard. I guess if the Canon wasn't so expensive, I'd quickly make the switch. I mean look at the prices of the new Sigma & Tamron 100-400s. That's quite a chasm.
