I’ve got a D200 and the 70-200VR.

I’ve done a search and read all I can find on TC’s. No need to
comment on f stop loss, focus hunting, etc.

I’m hoping someone who has the TC 17 and TC 20 can shed some light
on this question.

Considering the TC 17 has better f stop loss, etc., etc., Has
anyone made a comparison with the TC 17 and TC 20 by taking a pic
of the same object at maximum distance from a tripod? First with
the TC 17, then with the TC 20.

THEN take the image from the TC 17 and enlarge to equal image size
of the TC 20.

Is the TC 17’s image quality, equal to, better than, or worse than
enlarging the TC 17 to match the TC 20? Given that the original
difference is 510 versus 600, I’m wondering if the 90mm difference
can be made up by some minor interpolation in PS and keep (or
exceed?) the quality of the image taken with the TC 20?
