Canon SLR EF-mount zoom lens
The Canon EF 28–105 mm 4–5.6 is an inexpensive zoom lens often included as a kit lens with Canon 35 mm single-lens reflex cameras. 28–105 mm is a standard wide to telephoto zoom range. The Canon EF 28–105 mm 3.5–4.5 USM is a higher quality zoom lens with a better build quality. Currently every version of this lens is discontinued. Some versions of the lens may include the word macro or a flower icon which indicates macro capability, however due to the 1:5.2 image magnification ratio it cannot be considered as a true macro lens.
EF 28–105mm {{F/}}3.5–4.5 USM
This lens is a well-regarded consumer-grade lens. Its focus motor is ring USM, resulting in quick and quiet autofocus operation; this motor also allows the lens to offer full-time manual focusing. The lens uses internal focusing so the inner lens barrel does not rotate when focusing. This lens uses a "duo cam" type zoom barrel, this allows a more compact design, but still does not rotate while zooming.
This duo cam type zoom barrel is illustrated with the following two pictures: Image:Canon EF 28-105mm F3.5-4.5 II USM 28mm.jpg|Lens at 28 mm Image:Canon EF 28-105mm F3.5-4.5 II USM 105mm.jpg|Lens at 105 mm
There are three versions of this lens. The original lens had a five-blade diaphragm, 15 elements and was manufactured in Japan until 1999.{{cite web |author-link=Canon Inc. |author-link=Canon Inc.
EF 28–105mm {{F/}}4–5.6 USM
These are two inexpensive versions of the 28–105mm, cosmetically similar to the EF-S 18–55mm or the 90–300mm lenses which have the characteristic rubber grip on the barrel.{{cite web |author-link=Canon Inc.
