Very true! We spoke to enough people, including the technicians at the rental house, to ensure we wouldn't fry the sensor with the shots, and if you're careful about it, those shots are possible with the Alexa. Of course to get the sun proper, the rest of the sky goes dark, so it helps if there's some partial cloud cover to diffuse the glow and it looks great and surreal. Just keep the camera on the sun only for the duration of the shot and the instant you don't need to, pan away, is what I've discovered and the Alexa survived just fine. Wonder if they had the Alexa on the moon how it would handle? :)
Best,
