The Skink Pinhole Pancake lens is a little different than other pinhole lenses in that it has a modular design using disks, zone plates or sieves that can be installed between the retaining rings in the center of the lens. It’s constructed significantly better than a 9mm Olympus f/8.0 Fisheye Body Cap lens although physically it’s about the same size. The lens’s focal length is 16mm (32mm equivalent on Micro Four-thirds format) that I wish was wider and the aperture is f/90. Yup, not a typo.
Traditional pinhole lenses create relatively sharp images with exposure times ranging from one second to several minutes. With a zone plate or zone sieve, photos shot with the Skink Pinhole can be made without a tripod.
Since I didn’t either a plate or sieve, I increased the ISO settings on my Olympus OM-D EM-5 Mark I to get shutter speeds I could handhold and hedged my bets by shooting with a body with five-axis in-body image stabilization. Shooting from ISO 800 to 1000 I ended up—in Aperture Preferred mode—with shutter speeds ranging from 1/8 to 1/15 sec. Exposure for the above image was 1/10 sec at ISO 800.
Unlike the Oly 9mm lens, that has actual optics, the pinhole produced images that would best be described as soft. While working with the Skink Pinhole Pancake the images produced reminded me of Steigletz’s Photo-Secession. So I occasionally used Oly’s Soft Focus Art Filter shooting in RAW+JPEG mode so I had access to an unmolested RAW file.
