    TTL Flash for Mirrorless

    in Nikon

    Posted

    As far as I know the Z series cameras are compatible to existing Nikon flashes and can do TTL with them. I wonder how TTL flash is done with the Z. With film SLR the TTL flash sensor measures the light reflected off the film and shut off the flash when there is sufficient exposure. With DSLR it uses a constant power preflash, the light sensor in the viewfinder then determine how much flash power is need for the actual exposure.

    Since there is no dedicated light sensor on the Z, how would it do it?

    Possibly they measure the total lightness/darkness of the signals coming from the pixels of the sensor.

    As an engineer performing tests of conveying machines I would like to shoot high quality videos to use in promotion. It would be great to set up 3 or 4 cameras, each focused on a different part of the machine. We lack extra people to man each of those cameras. What equipment is available that would allow starting and stopping all cameras from one control?
