Inspired by the bifocal compound eyes of the extinct trilobite *Dalmanitina socialis*, researchers have developed a nanophotonic light-field camera with an unprecedented depth of field (DoF). The camera utilizes a spin-multiplexed bifocal metalens array and a multi-scale convolutional neural network to capture high-resolution light-field images ranging from centimeters to kilometers. This technology overcomes limitations of traditional light-field cameras, enabling simultaneous macro and telephoto modes in a single snapshot.
