Think I see what I would expect to see- More detail but less DOF in #1 ?

Brian,
The DOF will be the same but the position of the various flower parts, in spite of my efforts, within it differ. The focus was a little further away in the second image and not as much on the near petal detail as I would like. (The best of several shots). These flowers are very challenging for the use of DOF.
To be fair to the A7R images, the extender there was a Kiron, whereas the only 2x I could find for FD mount was a Canon Extender FD 2x B, whose quality compared with a Kiron I cannot vouch for.
Way, back, I did extensive tests with my best TCs and test charts, camera on tripod, and anti-shock delay or flash, for various apertures of a given lens. Viewed at the same subject magnification, I could find no difference in the rendering of the minutest printed dots on the chart, with or without a TC.
