Had the "Sunrise" and the "Holga" pinhole. Both are not bad. Buys this coinciding with the 100 My pinhole plate suits the MFT sensor size. Incredible: you get almost right sharp and high contrast photos. Processing: super. All-metal mount. The bayonet is as accurate, yet easy and free of play, as if it were made by Olympus itself. Take ISO 3,200. Then you need a tripod. Setting the image stabilizer to 18 mm. . Usually the exposure time is 1/4 - 1/8 sec Go to the Olympus-Bar free hand quite well. Believe me! "Nothing at ISO 3,200 too much resolution is lost." What! What resolution? This is a pinhole !!!
