We’re told to expect a new EF-S 24mm STM prime lens to arrive some time in the summer. The EF-S lineup is due for a shot in the arm, especially with the expected arrival of the EOS 7D Mark II.
We’re also told that a new USM motor will also be introduced some time this year, and it will be called “C-USM”, which stands for Compact Ultrasonic Motor. This technology is likely to first appear in a new 50mm lens.
