    I don't know... I think there could be higher quality MF lenses for $40...
    Never really understood pinhole lenses, except maybe as a cool self-made physics illustration, but in this case I would say it's being self-made that makes it cool, why pay for it?

    Seems the difference between the center part of the image and the vignetted corners too much for my tastes...

    Pinholes are fun... IF u experiment by yourself with some black paper, blu-tack and a needle. Pay for it readymade, and you missed the whole fun.
    As for pinhole optical quality, it IS a joke: even Leonardo D.V. knew that any magnifier/loupe would do better. Field diaphragm optional, though recommended.

    Kevin, what a fun video. I might need to play around with that. It's been years since I've worked with pinholes and that was using ASA 10 paper and film ASA 25-160, some with f/292. It never occurred to me to use digital at ISO 3600.

    Thanks mate, whole evening routine ruined thanks to you and Midnight Special (Vol 30) now playing on iTunes. I did a Google on pinholes the other day and found various ways of making a workable lens, mostly using a cap. I use a Holga and love experimenting with anything I can lay my hands on, also bought a set of ancient 46mm filters which fit the 20mm. Great vid by the way.

    Truly the fun is in the making. You are not limited to just one hole. Here is one with 4. It is 15 years old so please forgive the IQ. Sorry it's so crappy. Poor scanner and 5th generation image.

    4 pinhole with film. Car is parked.

    Single pinhole with film. "Water Park" - the Gary, In waste water treatment facility

    Slr magic also makes one that is 12mm and has glass covering the hole to prevent dust from reaching the sensor, which I would find appealing if i was in the market for one. Though I suppose that may affect the image.

    It can be seen on eBay. Here is a link to a review if anyone is interested:

    I bought a used Pinwide quite a while back here on the forum. It takes a lot of light, but it's fun to play with. It's sturdier and safer than homemade pinhole lenses - it has a lens-type insert so that dust can't get into the camera body. It comes in a nice little metal can that's easy to toss in a camera bag. :cool:

    Dust isn't a problem. With a flange focal distance is 19.25mm, the diameter of a correctly focused pinhole is 0.14625mm (0.00575") producing an aperture of f/94. A glass cover is essentially worthless.
