First, I wasn't talking about high sensitivity, but more DR. But it's not like the D800/D810 and such are terrible when it comes to sensitivity, far from it.
Disclaimer: I'm all in favor when it comes to Canon catching up to Sonikon, it's just that atm they don't seem to be willing or able to. And personally, I've been wondering for years why they don't upscale a crop sensor to ff, I'd love to have that for macro shots.
Maybe fine for some, but certainly not for me. I'd take the 36MP and high DR any day over 50MP and low DR from Canon. I'd even take 23MP and high DR over 50MP and low DR if I was forced.
I'm a big fan or more dynamic range and use Magic Lantern's dual_iso for about 1/3rd of my shots. But my guess is that Canon marketing research has gone into this very thoroughly, and the deep pocket enthusiasts on CR don't scale to the whole market.
I just talked to a landscape photog having to switch from his broken 5d2 to something else. He's now buying a d800 because for him, only the resolution counts - he was happy enough with the dr of mf film cameras. If Canon would offer 50mp for a comparable price, he'd been sold.
It is exactly the targeted audience for a high MP camera that probably MOST cares about high DR.
We'll see - my guess is that not that many people depend on more dr in a single frame
and wouldn't sell their mother or switch systems for 12ev (Canon) to 14ev (Sonikon).
