Hi Nenad, The light loss with the converter is 1,7 stops. The reason your camera shows 2 stops may be a rounding issue.
It says in the manual that the max aperture you can get with the converter is 2.8. It doesn't state the reason, but my guess would be that the diameter of the glass in the converter is limiting.
