That is not assured. Sony have reserved the stacked sensors to the A9 and A1 line thus far and I absolutely count on Canon to do the identical to vary the professional our bodies from the R5 and R6. In case you want blackout free, excessive FPS, and low latency; then go purchase the R1 or R3. In case you want a common do every thing digital camera, purchase the R5 or R6. Mirrorless our bodies are differentiated in lots of extra methods than we seen in DLSR, now the excessive finish can have quicker startup occasions, decrease latency, no blackout, greater decision and quicker EVF’s, and gosh is aware of what else to distinguish them from the 5-series and 6-series.
