Canon will definitely lose on pricing to Nikon just by how much. Judging from the £1,099 and £2,000, the difference is significant and crop enthusiasts with minor investment on glass might jump ship. That £1,000 spare can buy you a used Canon 100-400mmL ops uhmm Nikon 80-400mm VR
I do like the idea of 2x crop function for extra reach in an instant 1 hit button without taking the telephoto and putting in the 1.4x or 2x tc the only issue is how will the IQ hold.
Of course the IQ will take a big hit when using the crop mode. You loose many MP in resolution
