That's interesting. Thank You!
I have also been wondering why there is little or no DxO data for Nikon telephoto lenses tested on Nikon cameras compared to Canon telephoto lenses tested on Canon cameras. Is there a broader issue making it hard for DxO to test certain Nikon lenses ?
DxO is my primary lens performance reference. It's to bad that the data is so spotty.
