Here are a few images I took at Kissena Park while testing the Sigma 150-600 C for Canon on my Fuji X-T3 + Fringer EF to Fuji X adapter. I experienced fast and accurate focus on this cloudy day. Tracking birds in flight works superbly and I'd say I could not discern a difference in experience using this setup vis any of Fuji's faster focusing lenses.

Interesting that these kind of soft results would encourage you to recommend this lens with adapter. I think your results with the Fuji 100-400 are much better. Perhaps if you had decent light they would have been better.
Really? Perhaps you can elaborate on what you see as "soft" in these shots? Perhaps I'm going blind in my old age, but they look pretty darn sharp to me. Looks like your notion of "soft" varies a lot from mine.
Sharing an example of what you see as "soft" might clear the air a bit.
Jerry,
Are you viewing on your phone? Each and every shot is soft. Use your calibrated monitor and click on "View original size" Let it download and use the magnifier to get 100% view.
Start with the 4th photo, the mallards in flight. How does that look?
You and I have different standards, that's for sure, but soft is soft.
The Mallards in Flight shot was taken at 1/160s. I'd expect any BIF shot to be a tad soft at that shutter speed. The rest of the shots look fine to me, and while I might not be as picky as some here, I'm usually pretty good at perceiving softness in images. So, I'm still a bit confused as to your feedback here. FYI, I'm doing my viewing (at the present) on a 5K iMac.
Jerry,
I will try to clarify. When judging sharpness of birds I look for the feather detail around the eye and on the face. That's because the eye itself can appear sharp because it's shiny and pops out from the face. But, if I can see the detail of the feathers that ring the eye and/or feather detail on the eyelid, along with detail on the cheeks, then it passes the sharpness test.
It is not pixel peeping to view the photo at 100% and furthermore if the original photo out of the camera when viewed at 100% is not sharp then I delete it. Your standards and mileage may vary of course and I have no problem with that. You recently posted a beautiful hummingbird shot and I commented that it was "mighty fine". The bird itself was not sharp but it was close and the background colors made it a beautiful shot and a keeper. It was head and shoulders above any other hummingbird shot I have seen you post. I do not care for hummingbirds with grey/brown blobs for wings.
At any rate, if I were in the market for a super zoom I would be put off by Morris' shots because they are soft and shot at high ISO and then the noise was sharpened to crunchy so as to appear sharp.
I assume you will want to disagree and offer further extenuating circumstances like the shutter speed on the mallards in flight. That's fine but I have had my say and I'm going to just call it a day.
Happy New Year!
