Wide-angle lens

From a design perspective, a wide angle lens is one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length; this enables either large tilt & shift movements with a view camera, or lenses with wide fields of view.More informally,...

 in April 1989. Being of the "L" class, it is of completely different design and structure than the aforementioned 28-80mm 3.5-5.6 lens.

Description

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.
