Does anyone know for sure if the Focal Length info is correctly transmitted to the camera body (including the 1.7x magnification) when using such a combination, like with the 50-135 or 16-50 + 1.7x AFA? I am wanting accurate Shake Reduction when using the AFA with one of these SDM zooms.
According to the diagram on bdimitrov's web site, the digital info pin (7th) pin does seem to exist on both sides of the AFA (looking by eye on my copy). I am guessing/assuming that the focal length info would be passed through or processed by the AFA:

Also, does anyone know if the 1.7x fudge factor is calculated and passed along to the camera body correctly, too??? I am one of those type of people who needs to know for sure that something works correctly before spending any money. This is the theory, actual user experience would be appreciated to confirm my theory.
Also, this is not a question about autofocus and is not a question about other companies' TC's. Thanks for any help.
