Canon USA has posted a new video of their ongoing series, EF Lenses 101. This time the topic is Wide Angle lenses. These lenses are generally used to capture landscapes, cityscapes or a large crowd.
Matt Kloskowski is the presenter and he gives some tips on using wide angle lenses. Other videos on Fisheye lens, Tilt-shift lens and STM lens are here. You can read my FAQ on Canon lens recommendation and see my work on MichaelDanielHo.com
