In this series of articles, we will go through one by one, the recommended lens for all APS-C users. With it as a guide, you will be able to start building your own lens system. In this article, we will learn more about the wide-angle zoom lens EF-S10-22mm f/3.5-4.5 USM. (Reported by: Ryosuke Takahashi)

Correct aberrations of wide-angle lenses

This wide-angle zoom lens covers an angle of view equivalent to about 16 to 35mm in the 35mm format. It is able to capture a large area within the frame lines and the exaggerated perspective of a wide-angle lens visually extends the image. Another benefit of this lens is that you can make use of the compelling perspective at a wide- angle focal length in your photographic expression. Due to the optical characteristics of a wide-angle zoom lens, light fall-off at the peripheral areas of the image and chromatic aberrations are likely to occur. However, with the [Lens aberration correction] feature available on the EOS 100D, aberrations can be corrected in the camera by using the lens data, which helps to further enhance the image quality. This is an advantage that only genuine Canon lenses can offer.

The exaggerated perspective of wide-angle lenses extends an image visually, allowing you to include more scene within a frame. With the EF-S10-22mm f/3.5-4.5 USM, I took this shot of the building together with a red bus passing by from a super-low angle.

A wide-angle lens has a shorter focal length, which can make a close-up object appear larger than it is. With this effect in mind, I took a close-up shot of the binoculars on an observation deck against a wide background area. Although the actual size of the binoculars was not large, the unique perspective of the lens made it look as big as a cannon.
