Canon USA has posted a new video of their ongoing series, EF Lenses 101. This time the topic is Telephoto lenses. These lenses are used mostly to bring distant subjects closer, as in wildlife, bird or sports photography.
Matt Kloskowski is the presenter and he gives some tips on using Telephoto lenses. My favorite Super Telephoto lens is the Canon EF 200-400mm f/4L IS. Other videos on Fisheye, Tilt-shift, Wide angle and STM lenses are here. You can read my FAQs on Canon lens recommendation and see my work on MichaelDanielHo.com
