My first pinhole experiments results are here:

Photos from Alpha A200

Back in the day, I used an oatmeal can (cylinder) as a camera, photo paper as the negative, and needle-pierced tinfoil for the pinhole, and got decent ultrawide infinite-focus results.

More recently I've put a PinholeEdun Body Cap (reputedly f/181, effectively 45mm) on my Pentax K20D, and all I get is utter crud. I suspect the hole is too large for an APS-C sensor, that it might be more appropriate of a full-frame camera. I've tried my own tinfoil piercings in other lens caps with similar (or worse) trash. And the dSLR structure doesn't allow for closer placement to the sensor plane for a shorter focal length.

I've tried pinholes on surgically-altered 240x320 webcams, but the resolution sucks. I'm tempted to dissect a 1mpx digicam and apply a pinhole but I fear results similar to the K20D efforts. My sister gave me a beautiful carved hardwood 6x9cm pinhole camera a couple Xmas's ago, but now I can't find it. Embarassed

I am perplexed by failure. Where did I put that damn 6x9?????

Here are some pix I took with a pinhole lens made by Lenox Laser.
I glued a body cap on the side opposite the cap that the lens came with.
This way I can use it on both my Nikon D300 or Canon 550D.
Here are some samples:

I used the well known Vivitar pinhole lens Wink

May have had some camera shake Very Happy

Here's a couple examples I've done with a body cap and small chunk of soda can;

I recently moved the chunk of soda can to a lens cap, and I intend to take some portraits of people who think the lenscap is still on.

What about diffraction with such small apertures?

Clearly tons of diffraction Wink

Here are two test shots with a pinhole for L39 mounted on a Nikon 1 V1 using an L39-N1 adapter, FOV ~ 80 mm FF eq.
Even a 1" sensor can produce reasonable results with some PP, with some planning probably good enough for small still life prints.

Here are a couple shots with the pinhole moved to my lens CAP, in front of my 50mm 1.4. Pictures come out way sharper than with just the pinhole in front of the sensor.
