The 28mm - Where Wide-Angle Really Starts

Poon Foto.jpg (23k) Loading...
The 28mm wide-angle may be the most useful of all wide-angle lenses on a day-to-day basis - if you do a lot of group shots at night functions, you will appreciate more of this lens than the 35mm or the 24mm lens. It has relatively strong rendition of perspective, but has less tendency to exaggerate perspective as compared to a 24mm or 20mm lens, for example. Camera angle for distortion-free straight lines is not as critical as with the shorter focal length lenses.

If you are undecided about which wide-angle is best for your type of photography, it might be a good idea to take a look through the viewfinder with a 28mm lens. The image which you sees will have a more pronounced perspective rendition than a 50mm lens but not to a great extent. The main advantage of the 28mm lens is its ability to capture a fairly large subject area without creating undue concern over its perspective rendition. I have always thought a 28mm is far more logical than investing into a 35mm to handle all round photographic situations. A comparison of 24mm, 28mm and 35mm angles of view should give you an idea of how a 28mm performs.

With group portraits, a lens like the FD 28mm when used with imagination can mean a truly pleasing picture. You can move in close enough for facial detail and at the same time have sufficient pictorial coverage. And, giving some consideration to the subject's surroundings, the use depth of field to control the zone of sharpness at the sides and behind the main subject. Those who has faced the experience during a round table dinner function will appreciate more of its slightly broader coverage. Perhaps the only thing that you may want to take note of is sometimes the people or objects at the extreme two edges of the picture frame may be slightly distorted if the working distance is too close.

Another significant advantage of the 28mm focal length lenses is, all Canon Speedlites are designed to cover the field of view of a 35mm or longer lens. However, with the addition of their respective adapters, the Speedlites 277T and 188A cover the field of view of the 28mm lens. The Speedlite 199A with its wide adapter attached can be used with lenses down to 24mm in focal lengths. Using their respective adapters, the Speedlites 533G and 577G can even cover 20mm field of view. The combination of a Canon Speedlite 188A, 199A, 277T, 533G or 577G and a 28mm lens can be extremely valuable, providing good exposure and sufficient coverage.




Canon FDn 28mm f/2.8
New FD 28mm f/2 Lens

A very appealing lens blending good lens speed and a compact design. Using high refraction glass for improved optical performance. Alternating four convex and concave lenses in the front lens group serves to curb distortion, astigmatism and coma. The use of the floating system also aimed to maintain high quality pictures even at its closest focusing distance of 30cm, Compared to the earlier original FD 28mm f/2.0 lens, this lens is 24 percent shorter in overall length and 23 percent lighter.

New FD
28mm f/2.8 Lens

It is the most popular among the FD 28mm lenses. Quite compact, its overall length of 40mm and light weight of 170 grams made it the second lightest among the FD lenses. With a reasonable price and sufficient speed, it is one of the first and most practical choices for a wide-angle lens.

Composed of seven air-spaced elements, the 28mm f/2.8 possesses high contrast and superior resolving power. An outstanding feature of this lens is the judicious arrangement of two convex lenses, placing one in front of and the other behind the lens diaphragm to reduce spherical aberration arising from the three lenses in the front group with the convex lens directly behind the diaphragm.

Older Version: FD 28mm f2.0 S.S.C & FD 28mm f2.8 S.S.C

The high speed f2.0 enables Canon users has a good moderate choice between speed and performance. Both lenses essentially remain optically unchanged other than cosmetic changes, when they were 'upgraded to the FDn types. Click Here to the dedicated pages for these two older version of the FD wideangles. If prices were quoted much lower than the FDn version in the used market, these two older lenses may also be considered seriously.

Current Autofocus Version: Technical Highlight:

EF 28mm f2.8 : One of the most compact EF lens. Small and light weight. Incorporation of a glass molded aspherical lens element enables use of a simple effective 5-element, 5-group lens construction. Autofocusing uses an extension type focusing system.

EF 28mm f2.8.jpg
EF 28mm f1.8 : This is a new inclusion after the 28mm f2.8. It features a larger aperture. The optical system employs a replicated aspherical lens element suited to the large aperture. This attributes to the overall compactness and minimizes spherical aberration. A flare-cut diaphragm installed behind group 1 blocks unwanted light to ensure highest contrast. The closest focus distance, 0.25 m/0.8 ft, is the shortest in its class. Retrofocusing and incorporating ring USM to provide high speed AF. Also provide a non-rotating front lens group.

Quick data for reference: Focal length and maximum aperture: 28mm f/2.8; Lens construction: 5 elements in 5 groups; Angle of view: 75°; Focus adjustment: Overall linear extension system with AFD; Closest focusing distance: 0.3 m; Filter size: 52mm; Length x max. diameter, weight: 42.5mm x 67.4 mm, 185 g

Note: As at October 1999, there are two fixed focal length lens at 28mm for the EF autofocus lenses and high speed wide-angle lenses although one that is as fast as Nikon's AF-Nikkor 28mm f1.4 may still take a little while more before it can be materialized. But Canon also has its own high speed EF 35mm f1.4 L USM lens, which is a focal length that is very popular with photojournalists.
