I'm a Canon guy 100%! But more DR capability is always better if everything else is equal.
The analogy of a car with more HP is a good one. Don't always need it, but when you do, you are extremely grateful to have it. Extra HP can save your life and more DR can save a photo.
I hope Canon improves DR someday, but until then I will happily use my Canon 5D3, it is a great Camera.
"Actually, a car with too much power can easily be deadly if you don't know what you're doing with it."
"Back to dynamic range...I would completely agree with you if Canon's dynamic range were inadequate"
Regarding your first comment, I will take my chances with more DR. lol
Regarding the second comment, Canon DR is adequate, but I want great, not adequate.
Don't get me wrong, I'm very happy with my Canon, getting great photos with it, but there are times more DR would be welcome. End of discussion for me.
