Usually from the sensor. So MFD - lens length - flange distance = working distance.

That's how I know it also... And that's why knowing the "working distance" is crucial when it comes to macro lenses...



So for Canon EOS mount, minimum working distance for this lens = 380mm - 150mm - 44mm = 186mm (=18,6cm). And this is the distance you get max reproduction ratio of 1:1...
