Pinhole photography and mft cameras

Looks nice but not really worth $40 when it's so easy to do this yourself.

So how would you do this? Just honestly curious, because it doesn't look easy to me (and I've researched m43 flange to sensor distances to 0.05mm tolerances).
 
This is not a nail hole in your bodycap kind of pinhole device. That would result in a round photo in the middle of your frame. This is a wide angle recessed pinhole device that fills your whole mft sensor! The precision laser cut hole also produces sharper images. Only downside is the slow lens speed F96 which would require what - 4 more stops of liight than F16?'
I'd buy one for $40.
 
I did this DIY for just pennies using the lid form a small jar of mustard, a center punch and a hand drill. Works great!

Any one have any good tips for safely removing Grey Poupon from a sensor?
 
I have a jar lid with a very small hole in it (not made by puncture, made by making a dimple and then just barely sanding it until it makes a tiny hole, resulting in a very small hole.) Then I attach that lid to my Nikon adaptor (because it fits on there well) and seal it light tight with gaffer tape. Works great, fills the frame, and fills full frame on my Nikon 35mm SLRs. It's very wide but that's fine with me, I like that it's a little tighter because it means I can take photos of some more interesting subjects. In any case I could also stick a smaller jar lid right on the camera and it would work fine and be wider.

And I thought the 3D lens was slow at f/12.5!

F96 would be a little over five stops slower than f/16.

Not too bad for daylight (either lens.)

So in daylight at f/96 and ISO 800 you could do a 1/25th shutter, which should be sufficient to handhold with a lens that wide.
