How do you read "X" in 2X zoom camera?
"two by zoom"?
In BrE, it's a "two times zoom".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
In my world (AE), we would read it as 2 X. People will understand it.

I don't think all that many people in AmE would think of it as two ex, but two times....
I agree with "two times."
