It's even bigger than that, if you shoot live view. You can get 20fps mechanical. If you are shooting on a tripod or mono pod. This is quite doable. If hand held you can just use it hand held, which can work depending on the lens or use a Rear LCD viewfinder deal. I forget what it is called precisely.

That's a very big improvement.

But, and this is a big but. You have to ask yourself. Do I really need even 20fps? Even 16 is very fast. 20 is just crazy. 30 is just out of this world fast!

I know there are photogs that can use it, but I dare say many of us hobbiests (Although I am starting to transition to being a proper professional photographer) might not need 30.

Just a thought.
