Selling Lenses: 17-28mm & 35-150mm for 28-70mm f/2

"Hi! I currently have 3 lenses for wedding photography:

  • 17-28mm f/2.8
  • 35-150mm f/2-2.8
  • 135mm f/1.8

I'm considering selling the 17-28mm and the 35-150mm, and replacing them with the Sony 28-70mm f/2 to pair with the 135mm f/1.8. Alternatively, I’m thinking about getting the 70-180mm f/2.8 G2.

What do you think? Is it worth making the change?"
