I'm toying with the idea of drilling a pinhole in the center of my body cap for my D70s. I know it won't be good quality, but I want to try just because I've been doing a lot of pinhole photography with photo paper lately and it would be pretty cool to make a pinhole lens for my DSLR. I'm thinking the best build would be to start drilling a hole through and stop before I reach the other side, then poke a tiny hole with a needle. That way it will be the smallest hole possible, just so my images will turn out sharper. I'll probably then tape saran wrap on the outside of the cap just to keep dust off of the sensor. Does anyone have any suggestions for this? I'd like to see lenses and/or actual digital pinhole photos.
