You won't be able to see anything in the prism. The ground glass image will be extremely dim (f/150 or dimmer).
I can dream. On the practical level, I can set the camera on a tripod, use the normal lens to set up and then switch to the pinhole.


. Just how the year is going, I guess. Also had coffee can cameras in my car that I could have stuck in my knapsack if I'd thought of it. That first one from vedostuu above is striking!
