You'd run into diffraction limit for any reasonable pixel size long before the pinhole diameter gets smaller than the wavelength of visible light. The rest of your comment I fully agree with.
- Nition 8y agoAlso fairly rare to be shooting at higher than F/11 anyway, isn't it?
- petepete 8y agoIn normal situations yes. On occasions where you want to maximise DoF and focus stacking isn't an option (say macro shots of moving insects) it's a useful approach. The DoF when shooting macro can be fractions of a millimetre.
- brudgers 8y agoMy understanding is that the diffraction limit correlates with "sensor" size. f11 is about the limit for the APS-C sensors common in DSLR's. f16 is usable for 35mm film and full frame. With large format film cameras, f64 is usable, e.g. Group f64. https://en.wikipedia.org/wiki/Group_f/64 https://en.wikipedia.org/wiki/Group_f/64 There is a diffraction limit calculator at the bottom of this page, https://www.cambridgeincolour.com/tutorials/diffraction-photography.htm https://www.cambridgeincolour.com/tutorials/diffraction-phot...
