>>3360215>Given how small a pinhole aperture is, there's a good chance that you'll just have to accept some of the dust spots as a fact of life and clean 'em in post.Yeah, once you are past f/32 you are in eternal, "why is my sensor so dirty?" territory. The fastest F-stop pinhole I have is an f/106 for me 20mm focal length pinhole (pic and pics posted
