Canon Wide Angle Lens
A Canon wide angle lens should be a compulsory component in the arsenal of any photographer using Canon SLR gear because the wide angle is arguably the most indispensable of all lenses.
If you don't possess a telephoto, you can move closer to the subject or crop the image to fill the frame with your subject. However, there is no comparable substitute for a wide angle lens. If you want your landscape to include a sweeping, panoramic vista, you'll have to move back a very long way to fit in the whole scene with a standard 50mm lens.
Similarly, when photographing interiors, there's usually no space to move further back to include more of the scene. And you certainly can't post-process the image to "squeeze" more into the picture!
Fortunately, many single lens reflex cameras nowadays are sold with a mid-range zoom rather than the standard 50mm lens that traditionally came with SLR camera bodies. These "standard" zooms will often cover focal lengths from moderate wide-angle to short telephoto (e.g. 28 to 105mm), so in such cases the need for a wide angle is satisfied.
What is a Wide Angle Lens?
Wide angles can be broadly defined as lenses with a focal length shorter than 50mm. They take in an angle of view that's wider than the 46° covered by standard lenses and include more of the subject on either side, and above and below. The shorter the focal length, the wider the angle covered.
The problem with prime (or fixed focal length) wide angle lenses is that one is never enough. A lens that is ideal for people pictures just doesn't create the dramatic, soaring sense of space that you get with a shorter focal length.
However, such ultra wide-angles alter perspective to such a degree that they are quite unsuitable for images that must look natural -- as people pictures should.
This means that photographers who prefer prime lenses will need more than one Canon wide angle lens to cover a range of subjects that might include reportage-style pictures of people, architectural interiors and exteriors, and dramatic landscapes or cityscapes.
Here's a selection of popular and highly-rated prime Canon wide angle lenses that are worthy of consideration:

Shooting with a Canon wide angle lensWhen you're choosing a wide-angle lens, remember that the shorter the focal length of the lens you use, the more your pictures will deviate from what the eye sees. Armed with this knowledge, you can select the best type of lens for the subject you're photographing.
Choose the widest lens available when you want to exaggerate the sense of depth in a picture, or cram in as much of the scene as possible. If you just want to fit more of a scene into the picture, without distortion or emphasizing wide-angle effects such as exaggerated proportions, then opt for more moderate focal lengths in the 28 to 35mm range.
