Egami (translated) spotted a patent filed by Canon for a motorized mirror return mechanism. The advantages of such a mirror system are less vibration, and the possibility to miniaturize the whole thing. The solution described in the patent opens the way for a DSLR that is smaller than the Canon Rebel SL1/EOS 100D. The drawback is that such a mechanism can not achieve the same fps rate as classic mirror mechanism.
