Building a 4eyes Pinhole Camera (part 3)

I did get some interesting responses on the f295.org forum about my ideas for the 4eyes pincam.

Reading these comments, I did get an other idea: what if I make the focal length of each pinhole different? Four simultanious shots varying from wide angle to tele? A bit more trouble to build, but it could give a nice image??
The same camera but with different focal lengths could look like this drawing (below). I need to calculate how tall it can be before I get the "lens" with the bigger focal length on the image from the smaller focal length. Maybe if I made the bigger "lens" like a piramide with the top only 30 x 30 mm instead of the square 100 x 100 mm.
I should also not forget to give it extra exposure. With a longer focal length the f-number gets bigger and so will the required shutter speed. But this can easily be calculated.
To be continued.....
