I did not have the time (yet) to publish a complete
user review as I did with the Nikon 200-500, but, TMHO and with 400 gramms less, the sigma 150-600 C is optically about as good, with 150 mm more to use...
From this week, a bird in my garden, picture taken handheld with Nikon D500 and sigma 150-600 at 600mm.
The Original scene:
and a crop resized to 1000px longest side. Click on the image to open the 100% crop in full size. Feather detail is very OK to my opinion...
