Almost all mirrorless systems will stop down the lens when shooting normal sun exposures, until it's time to focus and expose the image. It's not unusual to see the blades close as far as they can during normal live view operations. They then open for focusing and to the selected aperture for exposure before stopping back down to cut light to the sensor.
Hmmm, I tend to shoot into the sun a lot with my normal to wide lenses, and have never seen that happen on my A6000. My 70-200 is used on an LA-EA2 (A to E mount) adapter, though, where the aperture is always fully open until it closes down to take the shot, DSLR style. The 500mm is a fixed aperture lens, too.

I suspect that pointing a telephoto for prolonged time into the sun will work as a magnifying glass and might overheat your sensor...
Yup, that's what I'm afraid of.
