Kikki, I moved your post to its own thread as it had no bearing on the matter being discussed where you posted your request.
What you’re after doesnt exist, at least not in quality lenses which you make reference to. For wildlife, birds etc in terms of versatility the 100-400 would probably be the best choise although the two primes would probably give you better IQ.
Landscapes you would have to look at the 17-40L, 16-35L in the pro lenses or in consumer lenses, the Sigma range, or Canons 10-22 which has very good ratings.
You dont mention what body you have and some of the lenses I mention are EF-S lenses which will only fit onto crop bodies.
