Acording to the FAQ, the Pinsta aperture is f/229 - but I guess that is for the 4x5, correct? With the 8x10 back and the new 0.52 pinhole, what is the correct aperture?
Bruno, Dave, I made a huge mistake! For some reason, I was looking at completely faulty info on my last comment (which I will delete after I post this comment, just to avoid confusion).The focal length of the 4x5 is indeed 80mm's. With the 0.35mm pinhole this is F229, as I stated. The 8x10, however, has a 170mm focal length and comes with a 0.52mm pinhole which makes it F327. If you use the 8x10 with the 0.35mm pinhole then it is F486.I sincerely apologize for the inconvenience this may have caused!
