The problem with using a pinhole to photograph the sun, first, the sun will be shining directly on sensor. Without solar protection, it could ruin the sensor.

I don't think that any pinhole that requires exposure times like an f/128 lens or slower is going to have any problem with the sun.

The real problem with such small apertures is that the dark current noise is going to swell very fast compared to the exposure unless the ambient light is very bright.
