Yes, that sounds great. But, please keep in mind that that $1,800 lens performs on par with a $900 Sigma lens. So, if you put a $900 Sigma lens on a 20 mp 10 fps Canon 7DII, you have about the same level of performance for well under half the price.What you mean relative to FF sensor?
The way i look at it: i have 61MP / 10 FPS full frame quality at 200-600mm and APS-C quality 22MP / 10 FPS at 1000mm, still pretty amazing. And 1.3 crop gives 30MP / 800mm / 10 FPS. All in a single camera with an $1800 lens.
