Nikon says that, based on internal testing, it expects the Nikon ZR to be able to record continuously for up to 2 hours and 5 minutes in 6K resolution at 59.94 frames per second in R3D NE at an ambient temperature of 25 degrees Celcius, despite the fact it is a very small camera with no active cooling. “As you can imagine, it was very difficult,” Noriaki Mochimizo, ZR Project Manager, tells PetaPixel during an interview at the IBC Conference in Amsterdam earlier this month regarding the ZR’s development and its ability to eschew a fan. By having new heat dissipation pathways, we were able to achieve this level of performance despite the compact size,” Mochimizo says. Not only can the camera record for such a long time, it has slightly better dynamic range than the Z6 III, which uses the same sensor. “We optimized the essential dynamic range of ZR to integrate RED color science and the base ISO and R3D NE codec records data by allocating the sensor’s dynamic range from highlights to shadows and achieves the wider dynamic range,” Satoru Takeuchi, Section Manager of 3rd Development Section & 1st Development Department, adds.
