Modern cameras have come so far they no longer need lenses: https://digital-photography-school.com/make-pinhole-camera-dslr-body-cap/
I remember seeing much sharper examples, but these are a blurry disappointment.
I did pinhole photography a longtime ago.Pin holes have been around as long as I can remember. They aren't new or modern at all. The fact that a pin hole acts as a lens is how I watched the solar eclipse back in the early 1990s in Colorado.
Each hole would create an image which might be interesting in and of itself.Yea, I know. I just thought it funny how you can forget the lens and drill a hole in the cap on a $3000 camera. I remember looking through a tiny hole I'd make with my fingers a lot when I was a kid. I could seem to zoom in or out without ever loosing much sharpness as I changed the focus of my eye.
I wonder if more than one hole in series or parallel and of varying sizes would allow greater control and sharper images?
Try it. I would recommend Dragon Lasers BE. It is however just 2x. But it has wide diameter, therefore the image will be less deformed. I would recommend you to get proper lens instead. You can get cheap lens for old 35 mm film cameras. Optics there is just awesome. Just make sure you can set aperture, for some electronic apertures you would need reduction.There's lots of talk about beam expanders on lasers, but how about using them on small cameras? Are the optics high enough quality? I assume so. Would a BE be compatible with camera optics? The idea would be to just slide a BE over a pocket camera's telescoping lens and maybe using magnets to hold it on, for the purpose of improving lighting conditions. Where can I find a good one to try? Ideally the small lens would be around 15-20mm, and the big one around 40-60mm.
