The Canon EF 28–105 mm f/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 f/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[edit]

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:

There are three versions of this lens. The original lens has a five-blade diaphragm and was manufactured in Japan until 1999.[1] The second version (from 1999-2002) featured an improved 7 blade aperture with metal replacing plastic on many of the zoom components and "MACRO" instead of a flower marking the side. There was no "II" marking on the bezel yet, but "LENS MADE IN JAPAN" was clearly stamped on the opposite side of the bezel.[2] The Japanese version is considered the most collectable, as it was still manufactured in their primary lens factory in Japan. The third version (from 2003-2010) was manufactured and assembled in Taiwan with a 7 blade aperture, MACRO on the side, a textured case, "II" added to the description on the bezel. "Made in Taiwan" was stamped on the base of the lens. There was a final variation during the last 3 years of production where they replaced all of the gold lettering on the case with all white lettering (to cut costs).

EF 28–105mm f/4–5.6 USM[edit]

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.[3] While retailing for around $100 less, these lenses have a decreased f-stop range and cheaper build quality (with a chrome-plated ring). The first 4–5.6 version has a DC motor for autofocus, while the second version uses a micro-USM, instead of ring USM that the 3.5–4.5 models use.
