I would also like to see some results of the 100-400.

I don't understand DXo's "Score" In this comparison, the Canon 55-250 has equal or better individual metrics compared to the Nikon 55-200, but the Nikon gets the higher "Score"?

Does anybody know how the scores are arrived at?

I ignore DxO's overall 'scores' (useless) and just look at the test data (very useful). If you want to know how the score is obtained they do tell you in the 'insights', but who cares how a lens (or camera) performs in a made-up metric?

If you are interested, they say the score measures the amount of information the lens + sensor capures.

When you get down to the nuts and bolts of photography, the results depend on the 'nut' behind the camera!

See the 'Plan' in my 'Profile' for my current equipment.
