Since you already have the 18-55mm range covered, you might want to
cover the 70-200 mm range with 70-200 F/4 L USM or go with its big
brother 70-200 F/2.8 L USM. to extend the capabilities of the camera
and photographer first, and then back fill with a 16-35 F/2.8 for
more low light performance and smaller Depth of Fields, and finally
replace the 18-55mm with the top notch 28-70 F2.8 L USM.
