It seems the Sony RX100 V is not only improved in recording time but also on resolution. Our reader “slowmosage” sent us his new findings on the official manual and in fact Sony states much higher resolution read out for the HFR mode at 480fps, 500fps, 960fps and 1000fps than the RX100 IV had.
The increases are not trivial and shows that the actual readout in the horizontal at 500fps and 480fps is the same number of pixels read out at the near full HD 240fps and 500fps 1824*1026. This is a big improvement compared to the previous HFR modes and confirms that the resolution seen in the sample footage not only looks better but it is based on more pixels read out.
