Canon has a 250-megapixel sensor that fits in a DSLR

Canon has announced a “250-megapixel” image sensor that would fit into a consumer-grade DSLR camera. The Japanese camera maker says the new APS-H CMOS sensor enables “distinguishing of lettering on the side of an airplane flying at a distance of approximately 18 km [11 miles] from the shooting location.” As well as being the densest sensor of its size, it’s also extremely fast. It has a readout speed of 1.25 billion pixels per second, meaning it can shoot its super-high-res images at up to five frames per second.
