[MkII]

An example of what I'm aiming for: http://www.apug.org/gallery1/showima...mageuser=33351

And I think the question I was trying to ask was 'does the absolute size of the pinhole make the difference or is it just relative?'. If it is only relative then the effect for f138 would be the same at both 25mm and 80mm focal length. At what point does the absolute size of the pinhole start to cause problems, 1mm, 2mm, 10mm?
