According to a rumor from earlier this month, it was suggested that Canon could be working on a new professional EOS R camera that could feature a hybrid EF/RF mount. Now according to a report from Canon Watch, it seems that another possible rumored feature of the camera is a “moving sensor”.
The report claims that this moving sensor is what will help make the hybrid mounting system works. This is due to the fact that EF and RF lenses are made differently. By using a moving sensor, it can help to move the sensor back and forth to adjust for the flange distance between the two lens types.
