Canon has released a new firmware for their popular C100 camera. The Canon EOS C100 firmware is exciting because it allows the camera to support continuous focus tracking of moving subjects.  Supposedly, you get the best results by using lenses with Stepping motors, such as the EF-S 18-35mm Canon lens.

While we’re not sure how well the camera will be able to auto-focus on moving subjects, we can’t wait to try it out! Check back soon and we’ll post the results!
