The EF 28-80mm f/3.5-5.6 is a zoom lens produced by Canon Inc. for their series of EOS single-lens reflex cameras. Canon produced eight iterations of the lens from 1989 to 1999.
The other 28-80mm lens is the Canon EF 28-80mm f/2.8-4L, which was an EF mount wide-to-normal zoom lens introduced by Canon in April 1989. Being of the "L" class, it is of completely different design and structure than the aforementioned 28-80mm f/3.5-5.6 lens.
The first iteration of the f/3.5-5.6 lens is identified by the metal mounting ring (the later versions use plastic mounting rings). This version also has a focus distance window and the USM allows full time manual focusing. It is also considerably larger than the later versions due to the internal optics being different as well. Both use filter size 58mm. Production of the first version ended in (approximately) 1995. Both versions have been included as kit lenses at one point in time or another.
The 'L' lens is identified by a red stripe round the lens barrel. Production of this version ended in approximately 1996.
