TTL Flash with Mirrorless Cameras?

5 years 6 months ago #610100 by Brandon F
So what I'm reading is that the new Nikon Z series cameras will work with existing Nikon flashes.  The cool part is that they speak about these being able to do TTL.  So correct me if I'm wrong, a DSLR will use a preflash, while the light sensor in the viewfinder does it's thing to figure out the flash power that is needed to get the right exposure.  SO, seeing there is no dedicated light sensor on the Nikon Z series cameras, whats the trick to being able to pull this off?

The speed of the light, and electronics....No trick at all.

Why so serious?

It works the same as it does with a DSLR.  The shutter opens, the flash fires and the shutter closes when enough light has reached the sensor.  As Effron says, the electronics handle things.  If I were to choose the most important developments in photography over my life time, I would rate digital imaging as the first and TTL flash as the second.
