A photographer friend and I took photos at an event organized by the Misalignment Museum in San Francisco, California.
I took this shot with an ultrafast f/0.75 vintage X-ray lens, a German made Rodenstock XR-Heligon 50mm f/0.75. The center is surprisingly sharp within the narrow DoF band of 3 mm. The outside is blurry, and has strong vignetting, even when mounted on an APS-C camera.
This vintage lens was used for X-ray machines before the digital age. The flange focal distance is less than 10 mm, e.g. too short for Sony E-mount, which has 18 mm. I adapted (aka abused) a Leica M39 to E-mount adapter for this X-ray lens. I gained 5 mm by placing the lens inside the E-mount, resulting in a 13 mm flange focal distance. Close enough, but still not to the point where I can focus to infinity. With this setup the focus distance is 36.5 cm as measured from the front of the lens. This lens has a fixed focus distance, e.g. I have to focus with my feet or tripod, which can be challenging with the very shallow depth of field of 3 mm. The lens is always fully open since it has no diaphragm. See photos of lens on Facebook at bit.ly/2VIsvJe
I processed a balanced and a photographic HDR photo from a JPG exposure, blended them selectively, carefully adjusted the color balance and curves, and desaturated the image. I welcome and appreciate constructive comments.
