Canon FD 28-55 f/3.5-4.5 zoom lens

 

During the early days of development of zoom lenses, much due to the resistance of general opinion where zoom lenses were of inferior quality and thus most manufacturers preferred an approach of 'safe and sound' research and development was focusing onto some middle-of-the-road optic such as wide-angle to standard zoom lenses that falls around 28-55mm or 35-70mm range.

Canon has a FD 28-55mm f/3.5 - 4.5 zoom, where it comprised of 28mm, 35mm and 50mm focal lengths, spans the range between a moderate wide-angle and a standard lens with a zoom ratio of 1.96 with popular' macro' (Close focusing) capability. It employs with a 3 group zoom systam design that have greatly reduced the size and weight in comparison wirth previous model of the same zoom ratio. In fact, the first zoom with such a zoom range was a 28-50mm f3.5 which can focus down to 25cm from the film plane and employed with two group zooming system.

Most of Canon's fixed focal length lenses are designed so that the closest focusing distance is approximately ten times the lens' focal length. For example, the closest focusing distance for the 28mm fixed focal length is 30cm (about 12 in.) and for the 50mm it is 45cm (about 18 in.). Due to aberration corrections this principle applies, in the case of a zoom lens, to its longest focal length. Thus with the 28-55mm zoom lens, the closest focusing distance is based on the 55mm focal setting. However, this results in a difference between the closest shooting distance of a fixed focal length 28mm lens and that of the 28mm range of the 28-55mm zoom lens. To overcome this discrepancy, a special macro focusing mechanism was developed and incorporated in this zoom lens enables close-up shooting.


This lens had adopted the similar concept of the more impressive 20-35mm f3.5 L featured elsewhere on this site, where the three most popular wideangle lenses of 24, 28 and 35mm were covered. This lens is looking more towards for those who may not be favouring the slight distorted image of the 24mm and replaced the longer focal length to 50mm instead of 35mm found on the 20-35mm zoom. This lens packed a lot of features and an impresive specifications list you would expect it to be a very bulky zoom. However, it happened to be light, compact and covering these three popular focal lengths. But somehow, it was not that popular as Canon thought it would be. Basically, I think the cause was most likely its longer focal length having a reach of only 50mm, which is neither long nor short for comfort and it was made even worst with the small aperture of f4.5 when used at the 50mm setting. One would imagine for whoever that has invest into such a zoom lens would have difficulties handling focusingthrough the viewfinder, and most likely the split image rangefinder will be darken, especially when used with Canon SLRs not utilising the New Split focusing screen, like the A-1, AE-1, AT-1 and AV-1 models. Anyway, the strongest asset of this lens is still its price and compactness which may appeal to those who prefers to travel light or one that was strapped with limited budget to spend on additional lenses.
