Thanks, this was what I wasn't sure about. What a shame it stops down to minimum aperture.

Hi all, I am new to this forum. I just picked up a 70-200 f2.8 Tamron. I'll eventually pick up a modern teleconverter that allows auto focus and transmits all the info from the lens to the camera.
But for the moment I happen to have a very old 2X APX Teleplus MC4 teleconverter kicking around so I threw that on to see how it works and surprisingly it is not too bad when used with the stop down metering green button like you would a manual vintage lens.
The one problem is I have no idea what aperture I am on. Can anyone help with this? I believe if I set the aperture when the lens is on without the teleconverter then turn the camera off and throw the converter and lens on, then turn it back on, the lens should have the same aperture as when I set it without the teleconverter?
Does anyone know if this is true, or if there is another sneak around? Surely someone out there has played around with old teleconverters on digital dslrs? Although I couldn't find anything on this out there in webland.
Any help would be greatly appreciated.
Cheers guys & girls.
