A couple of days ago I attempted to shoot some video of the Sun. With the 70D 3x digital zoom and the 100-400mm lens it was possible to have the Sun fill the frame. I guess the equivalent focal length used would have been 900-1000mm. That bit worked out well. Unfortunately, in spite of the sturdy tripod, the gusty wind gave enough vibration to make the video unwatchable. On the other hand when I grabbed a still from the video it was clear enough to use:
This still shot showing a line of Sunspots is as grabbed from the video with no processing or cropping.
For anyone who hasn't seen the previous post on photographing the Sun please note that the only safe way to keep your eyesight and an unfried camera is to use a solar filter designed for that job.
