The 50-400 looks extremely soft in that comparison against other 100-400mm lenses.
From the-digital-picture.com, left Tamron, right Sony GM (both at 400mm):
Maybe a result of the short test distance? But if it was indeed 16'ish meters then this can't be the reason...
If a lens doesn’t implement floating elements the close performance tends to be shit. I’m not sure that’s the case here.
It looks like the lens is just softer than the GM glass. It’s half the price of the 100-400GM, I wouldn’t expect it to perform similarly.
Except that some reviews show that it performs excellent (e.g. Dustin Abbott).
And when comparing the MTF of both lenses, they should basically perform the same:
The MTF charts you posted are close to useless
We have 100-130lp/mm sensors (7iv, Riv and everything in between), so MTF charts testing at 30lp/mm is not helpful
