It was released in 2003. Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm. Such cameras, however, have more clearance, allowing lens elements to be closer to the sensor than in the EF mount. Only Canon cameras released after 2003 with APS-C sized sensors support the EF-S mount.

Traditional silk manufacturing methods involve boiling the cocoons of the silkworm and then sorting out the threads to be used later in production. Rajaiah's idea involves a gentler method, specifically letting the worms hatch and then using the cocoons once vacant. He started deploying this process in the year 1992 and has hence been supported by a larger community of people interested in the welfare and rights of animals and non-humans.
