I have made the following comparisons - sorry not the lenses you are interested in, but perhaps the conclusions might be similar.
- My 200 f2.8 (prime) with 1.4x teleconverter is not quite as good as the plain 200 f2.8 taken from a closer distance. Resolution is surprisingly close, but chromatic aberration is noticeable with the 1.4x and largely absent without it... The 1.4x combination would be acceptable for many purposes with careful PP.
I understand that the 2x TC noticeably affects image quality.
I can confirm both of these observations.
