After a lot of experimentation with zone sieves on Leica rangefinder cameras, I found that this one works best. Under normal lighting conditions without high-contrast or reflective areas, the zone sieve will just behave like a pinhole, just a little softer. Pronounced highlights and visible halos only appear when the available light becomes stronger and contrast increases.Skink Pinhole Pancake
