Canon Explorer of Light Ken Slutke about how to photograph the Solar Eclipse. Slutke was interviewed by Time.
He gives some recommendations:
Sklute recommends three Canon models at different price points and skill levels, as shown in the video above. The Powershot Sx60 is a beginner level point-and-shoot bundled with a solar filter that can be purchased for $499.99. For the next step up, Sklute suggests the Rebel T7i (camera body only) for $749.99. On the more professional side, you can buy the 5D Mark IV (camera body only) for $3,299.
Once you have your camera, the next step is choosing a lens. You’ll want at least a 300 mm focal length to get a good-sized image of the sun in the frame, Sklute says. Focal length refers to the distance between a camera’s sensor and its lens. The longer the lens’s focal length, the larger the sun will be in the final image. Those who are hesitant about investing in an expensive lens may want to rent one instead.
The total solar eclipse will be visible in the US on August 21, 2017. The Canon Digital Learning Center has a lot of resources to get you ready.
