Is it possible to turn off all the power-consuming features of Nikon Z 6 / Z 7 cameras when it flows in manual mode? Since it is not necessary that the EVF monitor or monitor be turned on, the autofocus or the measurement, the battery life should be better than an equivalent digital SLR because it involves fewer moving parts. However, I am not sure if this is possible? Has Nikon made this possible or will the camera still turn on the sensor to perform calculations and collect (unused) data for measurement, etc.? I plan to buy the Z 6 for accelerated photography and the battery life is important.
