The Canon EF 28-90 mm is a lens included as a kit lens with Canon EOS film cameras.
The maximum aperture is f/4 at 28mm, reducing to f/5.6 at 90mm. When focused at 90mm this will create background blur for portrait photography.
It is a very lightweight design, and has very fast auto focusing even without USM. Image quality suffers particularly between 28-35mm and 80-90mm however, and there is heavy vignetting when used wide open.
For digital EOS cameras with APS-C sensors, the EF-S 18-55mm lens covers the same range. This is due to crop factor. EF-S lenses only work with Canon 1.6x crop cameras, which results in an angle of view roughly equivalent to that of a 29-90mm lens on a 35mm camera. Like the 28-90mm, the 18-55mm is also a kit lens.[1]
