Ricoh Imaging announced that they are going to display a digital single-lens reflex camera and 3 new K-mount lenses at the 2015 International CES. They are all currently under development and no detailed specs are unveiled yet.
This latest EF-S lens offers a 35mm equivalent focal range of 16-29mm. The lens construction consists of 14 elements in 11 groups. By applying a plastic-molded aspheric lens element, it became smaller and lighter than the previous model.

Canon today announced that on April 22, Canon achieved production of one hundred million of its EF lens (interchangeable lens for the EOS series). As an interchangeable lens, EF lens for the EOS series became the most manufactured camera lens in the world.
