The monomer is allyl diglycol carbonate (ADC). The term CR-39 technically refers to the ADC monomer, but is more commonly used to refer to the finished plastic.
The Micro Four Thirds system (MFT) of still and video cameras and lenses was released by Olympus and Panasonic in 2008; lenses built for MFT use a flange focal distance of 19.25 mm, covering an image sensor with dimensions 17.3 × 13.0 mm (21.6 mm diagonal).
HCD lenses are optimized for slightly smaller image sensors covering 48×36 mm (1.9×1.4 in), [95] so the crop factor for HCD lenses is slightly greater at 0.72. With these sensors, an 80 mm lens would have the equivalent coverage of a lens with a focal length of approximately 60 mm on a "full-frame" camera.
