Nicely post feuerschlange. I recently acquired a refurbished TC-14II via Adorama and have found that it works very well with the 70-200. Focus speed was just as quick with the TC on as it was without it. No apparent loss of IQ with the TC.
Taken w/D-700, 70-200 VR, TC-14II, no PP other than compressing for the web (clickable)
Thanks CK.
I guess, you didn't apply sharpening before compressing for web and output sharpening during compressing and gave the real naked file (heavily compressed though
).
If I am wrong, there could be something with your lens/ TC combo, I have seen with different TCs on my sample of the 70-200 (very soft or slightly oof).
The two TCs, I bought for this lens were really handpicked by me. The camera shop owner was already annoyed and thought, I am only to try and not buy. You really have to handpick the TCs. I do not recommend, to buy them online, if you don't have a save way, to return them.
The different TCs of the same type I tried, showed big differences in focus and sharpness. You have here really three sample variations (lens, TC and body), that might add up to the worst and are really brought out by the magnified rendering of the TC.
The slightest off from the combination nets you a soft photograph.
You can trick and fine tune focus on some bodies nowadays. This works only to a certain degree though.
The TCs are not too expensive (the TC20 being more costly). I really recommend, to buy them in a good camera shop and try them on site (used is no problem, the Nikons are built like tanks).
Also actually shooting with a TC is quite different, than shooting without.
Every TC limits the actual sweet window of the lens, also, when you might not think so on first sight (TC14). Some flaws of the lenses do get exaggerated. While a lens might be good at its widest aperture naked, this aperture might get very soft with TC. Stopping down helps a lot here.
The 70-200 looks horrible @ f4.8 with my TC17 (widest aperture) and tack sharp from f5.6 on.
I really had to trial and error, to find out the good range, to use it.
It took me one year, to find a good range for my combo, only to find myself always hitting the longest focal length lately.
I guess, its the same with cars - there is no such thing as "enough power".
