The versatility of having a range of focal lengths available for immediate use has made zoom lenses by far the world's most popular DSLR camera lens choice. In the not-too-distant past, choosing a zoom lens over a prime (fixed focal length) lens meant sacrificing image quality. Times have changed. Improvements in zoom lens design have brought the image quality delivered by these lenses to levels previously reserved only for prime lenses.
Canon's zoom lens selection is, as you can see, huge. That is a positive aspect – a reason to buy into the Canon line. There is a Canon zoom lens available for nearly every need, from general-purpose to more specific purposes.
The EF zoom lenses reviewed here are compatible with all Canon EOS DSLR camera models. The EF-S zoom lenses are compatible only with APS-C/1.6x sensor format Canon EOS DSLR DSLRs, including the Rebel/***D and the **D models.
