Canon EF-S 18-55mm lens
From Wikipedia, the free encyclopedia
The EF-S 18-55mm lens is a wide-angle to mild telephoto lens made by Canon Inc.. The lens has an EF-S mount to work with some of the latest digital EOS cameras.
The lens comes in two different versions differing only in the use of the ultrasonic motor. The USM-less version, being cheaper, is sold as a bundled kit lens with Canon's consumer digital SLRs.
Even though the lens can perform at f/3.5 on the 18 mm end of the focal range and f/5.6 at 55 mm, the lens gives much better results (in both terms of vignetting and chromatic aberrations) if stopped down to at least f/8. Stopping down to f/11 or more gives diminishing returns.
A good choice of lens to replace this one, or simply augment a photographer's collection, is the EF 17-40mm L lens, or the EF-S 17-55mm f/2.8 USM IS.
