Well, over at imaging resource - just compare it to e.g. the Olympus M.Zuiko 70-300mm at the long end.
A comparison with a prime lens is always a bit unfair IMHO since the scopes are different.
It is about as good as the Sigma 150-600mm C, Nikkor 70-400 VR, Tamron 150-600mm and better than the Canon 100-400mm mk I - and these are all "shorter".
Disclaimer - I have no clue at all about IR's test method - just comparing those charts.
