Re: Tamron 18-400mm vs. 100-400mm vs Sigma 100-400mm?

I can only comment on the Tamron 100-400. It shows really nice resolution even wide open in the center over the whole zoom range, even at the tele end (used on D7500, being a pixel peeper). However, to get the best out of it, some AF fine-tuning was necessary in my exemplar, and at the tele end, I struggle sometimes with my shooting technique (handheld) even with VR on.

Here I have a test picture (center crop, D7500) at 400 mm (F6.3 or F7.1) handheld where everything worked well:
