Not cheap but the only lens you’ll need
In my film days I shot only with prime lenses and never owned a zoom, the reason being zooms normally have smaller maximum apertures,often incorporate optical compromises, and shoot through more glass than a prime lens. That was then, this is now. Canon has overcome the small maximum aperture with the Image Stabilizer (IS). This means that if the camera tells you you can only shoot a particular scene at f/4 at 1/15th of a second which is very hard to shoot without blur, the IS compensates for the motion resulting from being handheld by actually moving the elements within the lens. The result is you can shoot at a much lower shutter speed and get away with it — a tremendous advantage for a lens that only goes down to f/4. The 17-85mm zoom range is equivalent to 28-135mm in 35mm. Seldom have I felt the need for either a wider or longer focal length and constantly switching lenses only adds to the dust problem inside the camera. And the image quality is superb as always. Canon optics have been ahead of Nikon optics for many years which accounts for why so many have made the switch from Nikon to Canon. And please don’t forget to order a UV filter with it. Put the filter on and never take it off.
