  • @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. :)
