How to use Super Wide-angle
and Wide-angle focal lengths for creative effects with your Canon cameras.
Both the super wide-angle and wide-angle
lenses are capable of capturing a larger angle-of-view than your own eye. They offer
endless opportunities of unique and interesting pictures. You can rely on Canon's
super wide-angle and wide-angle lenses to get impressive shots even in tight situations.
When it comes to photographing room interiors or architecture, the super wide-angle
lenses are hard to beat.
Once you have mastered the super
wide-angle lenses, a whole new world of photographic opportunities will be yours.
And the next generation of lenses to master will be the wide-angle types. Wide-angles
are lenses with focal lengths above 20mm and up to 40mm (anything of 41mm till 60mm
is considered as a standard focal length for the 35mm format).
Like the super wide-angles, wide-angle
lenses allow both the background to be in sharp focus as their short focal length
makes hand-held shooting easy. Bright aperture settings are ideal for natural lighting
conditions, making these lenses the right choice for night scenes or for shooting
indoors.
Super wide-angle lenses feature
a far wider angle-of-view than what the human eye is capable of, thus allowing you
to create pictures with interesting visual distortions. Compare the angle-of-view
of the human eye, which is around 50-degree, with that of a 20mm super wide-angle
lens (94-degree along the diagonal) or a 14mm lens (114-degree). This is like seeing
- in one glance - everything framed by your car's windshield from the driver's seat.
With the EF 15mm f/2.8 fisheye
lens, the diagonal angle-of-view is a full 180-degree - the entire scene in front
of your lens. Super wide-angles are lenses with focal lengths from 11mm to 20mm,
including full-frame fisheye optics. Any lens having a focal length of 10mm and below
is known as the circular fisheye lens since it shows the entire 180-degree diagonal
angle-of-view in the 24x36mm film frame.

These lenses offer more than just
wide viewing angles. Exaggerated perspective foreshortening effects make subjects
nearer to the camera appear very large, with a rapid decrease in size as they move
further away, as shown in the photos above. A pan-focus effect with everything appearing
sharp from foreground to background is thus easily achieved, even when shooting at
large apertures.
When using such lenses, the angle
of the camera, relative to horizontal, also has a significant effect on the resulting
image. By tilting the camera up or down just slightly, vertical lines will appear
to converge, or taper dramatically. The resulting picture will exhibit a strong perspective
distortion. By holding the camera level, a more natural feeling with minimal perspective
distortion will result.
Used to your advantage, the distortions
created by these lenses can help you create more dramatic pictures. The super wide
viewing angle means that by simply pointing and shooting, you can create an endless
variety of unique images. For the experienced photographer, mastering the super wide-angle
lenses means being able to take advantage of their special properties without letting
their distinctive characteristics dominate the resulting pictures.
