I have completed my lens series with a Canon EF 70-200mm f/2.8 L IS II USM as my first zoom telephoto.
Some reviews here:

• The Digital Picture
• dpreview

It’s big, it’s heavy, but it is extremely sharp, and the background blur at f/2.8 is just crazy.

Actually I was “pushed” to buy this lens because of some of the best landscape photographs (for my taste) I have seen made by Vincent Laforet, who is intensively using zoom telephotos….
