Canon to Merge Two Lenses Into an RF 24-70mm f/2L IS?

[neuroanatomist]

I can't see this happening if they want to compete against the 50-150 f2.0 from Sony which is way less expensive.

150/2 = 75
200/2.8 = 71.4

200/2 = 100

There's a big difference in the amount of glass needed to achieve 200/2 compared to 150/2 (the latter being similar to 200/2.8). Physics.

Also, what makes you think Canon's goal is to compete against any particular Sony product?
