I’ve been thinking for years now that it’s interesting that no DSLR maker has really implemented touchscreen technology. It seems such an obvious step, particularly given the resounding success of touchscreens on mobile phones.
So Canon have taken the first step, announcing the EOS 650D or Rebel T4i, which includes a complete touchscreen interface. It’s not a replacement for the usual buttons and knobs, but an optional way to use the camera.
They also introduced a new pair of lenses - STM or “stepper motor” lenses - which promise near-silent and smooth operation for video work.
