Assuming full frame:
Versatility: The MkII zoom trinity.
I might replace the 24-70 with the 50 1.2, though.
If I'm doing primes:
24 1.4L II, the 50 1.2L and the 200 f2L.
(I could possible swap the 24 for the 14… Tough choice!)
Would probably be the same, except I'd use the 10-22, and definitely the 14mm over the 24. (The others would probably be the same. Maybe the Sigma 35mm instead of the 50…).
Fortunately, I don't have to restrict myself to only 3 lenses… (Not that I even own all of these!)
