Good reply, good links, thank you. I can see now how under some conditions the sun could damage the sensor - or even burn a hole in it. This might be especially likely while using the monitor to compose the photo on a bright day.
But I doubt I would ever include the sun in a photo, set the shutter to 3 seconds (re fem2008
) and assume the result would be a good exposure. Not on a bright day anyway.
In the past I used an SLR with 50mm lens, polarizer (to knock off 1.5 stops) and film to take photos of the sun/sky at @ 1000/second @ F22. The result was acceptable. IIRC I didn’t spend much time looking through the viewfinder and I didn’t look directly at the sun. The sun was slightly (moderately?) obscured but visible through some clouds.
