for me the comparison was simple, even with all the problems you rightly make - could I identify the boats, see their numbers, see the people etc.

I'm a pragmatic photographer, I have a job to do and I want to know if my gear will do it, in this case the 50-200 does it as well as the 75-300 (making no claims of great images etc, I leave that to those who like to argue the minutiae of IQ and lpi resolution etc )

Its remarkable, as far as I am concerned, that at this distance and under these conditions I can read the text on the side of the lead boat in each shot.

The marvels of modern technology...

Had I had the EC-14 on the 50-200 then the boat numbers would have been blurred and the image less useful

As you may guess, when I got my 50-200 +1.4 I tested exhaustively the TC. And I arrived to the same conclusion that my fellows here at DPR: it is hard to spot the difference in IQ with/without the TC at the same focal lengths. The TC is excellent (and expensive!). The higher magnification pays off easily the small penalty in IQ. Same for the 2.0x.

Cheers,
