Most people are looking for at least one general purpose lens when they buy a Canon DSLR.
The heart of the focal length range targeted by Canon for lenses with this purpose is approximately 28-70mm.
The DSLR FOVCF (Field of View Crop Factor) comes into play here,
effectively requiring a shorter focal length range for 1.3x and 1.6x FOVCF DSLR bodies to yield the same subject framing.
When selecting a lens, I generally look for the highest image quality I can get in the most versatile and highest quality package I can get it in.
My personal highest recommendations for general purpose lenses are the
Canon EF-S 17-55mm f/2.8 IS USM Lens,
Canon EF 24-105mm f/4 L USM Lens and
Canon EF 24-70mm f/2.8 L USM Lens.
Prior to the introduction of the EF-S 17-55 and 24-105 L,
the Canon EF 24-70mm f/2.8 L USM Lens
was what I considered the ultimate general purpose lens.
I personally find the 1.3x field of view crop factor to be just about perfect with this lens.
I take a lot of people pictures and the slightly tighter framing provided by 1.3x and 1.6x FOVCF bodies works well for this purpose.
I use the Canon EF 70-200 f/2.8 L IS USM Lens
with more frequency on a full frame body, but still recommend the 24-70 as a one-lens-does-everything selection.
The 24-70's 24mm end is wide enough for environmental portraits and wide landscapes while 70mm makes a reasonable head/shoulders portrait focal length.
Group pictures, birthday parties, weddings, photojournalism, travel pictures ... the uses are endless.
The image quality from this lens is unsurpassed by any Canon EF lens containing this focal length range with the 24-105 L (next) being the only possible exception.
And with a fixed f/2.8 aperture, this lens is as fast as any zoom lens.
Build quality is excellent.
The Canon EF 24-105mm f/4 L IS USM Lens
joined my most-recommended list after the 24-70 L.
The Image Stabilization and additional focal length on the 24-105 offset (and for many situations surpass) the benefits of the fixed f/2.8 aperture on the 24-70 L.
Especially when shooting with a full-frame body, I find the extra 35mm of focal length on the long end very valuable in a general purpose lens - and especially for portraits.
Image, build and mechanical qualities of this lens are top of the line.
The 24-105 L's size and weight make it a very nice handling lens.
When using a 1.6x FOVCF body, we often want wider focal lengths from our general purpose Canon lenses.
The Canon EF-S 17-55mm f/2.8 IS USM Lens
(EF-S mount only) delivers excellent image quality, a wide aperture and an excellent implementation of image stabilization.
Fast, quiet and accurate Ring USM AF is a valuable asset of this lens.
Not everyone wants to spend as much as the above lenses cost.
For these people, I recommend the
Tamron 17-50mm f/2.8 XR Di II Lens (EF-S mount only) and
Canon EF 17-40mm f/4.0 L USM Lens.
Both lenses are very good values with excellent image quality and relatively small size/light weight.
Some additional good Canon general purpose lens choices include the
Canon EF 28-135mm f/3.5-5.6 IS USM Lens and the
Canon EF-S 17-85mm f/4-5.6 IS USM Lens
(for EF-S capable DSLRs only).
For the lowest budget, the Canon EF-S 18-55mm f/3.5-5.6 IS Lens is my recommendation.
All three of these lenses offer one of my favorite features - Image Stabilization.
Pair a general purpose zoom with one of Canon 70-200mm L lenses for a great kit -
the Canon EF 70-200mm f/4 L USM Lens is a great value.
