@RobinSchouten its always the focusing distance from sensor / film :)
Because every lens has different length (+changes during zoom or focusing), so it would be unusable to compare, if MFD would be taken from last element or somewhere else :)

@xmeda Ah I didn't know they measured from the sensor. Really amazing.
Thanks for the vid.

@RobinSchouten yes real, this lens has 20cm focusing distance and this is measured from sensor plane.. so when extended, you can focus like this.
Is this real? If so, great!
I ordered this lens, it will delivered tomorrow. :)
