And for all my bashing of their absurd ranking system, you have to tip your cap to DXO here -- no one else has anywhere near the number of lenses tested on the 5DS or 5DS R as they do.
So skip the score/ranking nonsense and mine what insights you can from their more detailed sharpness maps and such. If you are pondering a specific lens's 'future-proofness' of moving to a 50 MP rig, you know have a lot more data than you did yesterday.
For lenses, the graphs I care about most is sharpness wide open and the overall score.
I'm Surprised how poorly the Tamron 24-70 performed (24 perceivable pixels) compared to Canon's 24-70ii (33 perceivable pixels)
Gotta Love Canon's 24-70 and 70-200 combo!!! It scored very very well.
I posted a few selected lens re-test scores here before DXO formally made a page for this story:
