I have a Nikon 70-200mm f2.8 VR II and am considering adding a teleconvertor or two -- specifically the TC14E II and TC20E II -- to my kit to give me the versatility I would get in a smaller package than carrying an added lens. Do any of you have both of these and if so, can you give me your critical assessment of their performance. It would be great if you aer using them on the lens I have (70-200).

I have both and primarily used the 1.4 x TCII on my 70-200 VRII because my 2XTCIII made my D200 AF hunting too easily. I now have a D800 and use both as well.
N.B. I bought these TCs primarily for use on my 500 VRII where they perform excellently ( 1.4TC) and very very well (2TC). I have the TC2 III wich is known to be much better than version II.
Quality-wise, there is a visible difference between the two, but it isn't that big and practically disappears at f/8 or when downsizing from 36mp or do some sharpening.
Another point, as you know very well, the 1stop difference means slower shutter speed or increased ISO meaning potentially more blurred image or noiser image. This may be important for some older sensors (like my D200) or when handholding.
I have both and will keep both (useful for both 500 and 70-200). I would personnally say that the quantity of light available in your planned shooting environment and the required max reach are a more important selection criteria than final IQ.
The short answer (see that other thread for more of a discussion) is that with the TC14E image quality is minimally harmed — you almost cannot tell the difference TC off or TC on, except that you are that much "closer".
Alan, you typed "TC20E II" — that's "two" — and if you mean that, forget it. You want the current version "III". I find the results quite good, especially if you can stop down. The tradeoff for some loss of IQ, of course, is you have a handholdable 400mm!

I can't offer lens specific advice since I only have the 70-200 version I. However, with my version (and all my other long lenses) the 1.4 tc is superb. With the TC20E III I am totally pleased with the results on my 70-200, 200-400, 500, 600. I previously owned the TC20E II and considered it essentially useless. The TC20E III I consider superior to my TC17E.
Do not make the mistake of purchasing the TC20E II!
Agree with you on the TC20E II. I lost contact with what was happening in the camera market and didnt know there were some different versions of the TC20E. ) I have the TC14E(magic),TC17E(its acceptable),but,I never liked the T20E. Wasn't aware of the different versions.

I'm curious in what way you find it superior Jim. I use the TC17E a lot with my 70-200 2.8 and I am pleased with the results, but I could use a little more reach - and wonder if it is worth the money to purchase the TC20E III. I would regret loosing more sharpness and quality.
Yes, for the half stop which allows for much more reliable autofocus. Also when the tc20 would put me out too far, I find about 1000mm to be about the maximum at which I can take acceptable shots. Although I can get out to 1800mm with my DX cameras, they would need to be embedded in concret
