I can't remember who was mentioning trying out DA lenses on FF with a TC the other day, but was wondering which teleconverter you were using.
It was me! I used the Tamron-F AF 2X Pz-AF BBAR MC7 Teleconverter with the SDM DA* 16-50mm f/2.8. I posted a couple of samples in my flickr account. I still have pending to do the same with the SDM DA* 55-135mm f/2.8. Hopefully this week I will take the shots and prepare a post with all the samples during the weekend or the next at latest.
I was very happy to learn that the "X" factor was not of 2X but for around 1.3X, meaning that FOV of 16mm with the TC on the FF was equivalent to the FOV of 21mm in the APSC-C aprox. with the loss of about 1.5 stops. but with no vignetting at all, so to me that was a win all around.
