I presently use a Nikon 500mm f4.0 vr lens on my d4 for my bird photography. I have a tc 1.4EII converter and a tc 1.7EII converter that I use with the Nikon 500 lens. I have had excellant results in image sharpness and auto focus using the tc 1.4, and a little lesser image quality and auto focus accuracy and speed using the tc 1.7. It seems the tc 1.7EII needs fairly good light for accurate auto focus on the d4, more miss focuses than I like depending on the light.
I have a chance to buy the tc 2.0EIII converter so here is my question. Is the tc 2.0EIII better than the tc 1.7EII concerning image quality and auto focus accuracy. I am assuming speed between the tc 2.0 and tc 1.7 is about the same and not ideal for birds in flight or anything moving very fast?
I can't speak definitively about the TC-17e as I don't have it, but I routinely use the TC-20eIII with a 400/f2.8, and not even on a D4 - on a D3 and even a D2x. My primary application is motorsport, which I assume qualifies as "moving pretty fast." AF speed is not equal to the same camera and lens with the TC-14eII (which I do have) but it's good enough that I use the TC-20eIII about 4x as much as the TC-14eII. Image quality is at least excellent as long as I stop down a stop (ie effective f/8). IQ wide open (f/5.6) is not bad, but is visibly better stopped down.

I use my 500 f/4 with both the 1.7tcII and the 2.0tcIII usually on a D3s. To me the image quality with the 2.0 is actually superior to the 1.7. Neither one is ideal for BIF. The 1.7 works better on autofocus accuracy and speed on my D3s because that setup has a maximum of f/6.7 (in other words you lose one and a half stops of light) while the 2.0 has a maximum of f/8 (losing two stops of light).
On your D4 you should have better autofocusing at both f/6.7 and f/8 maximum than I do with my D3s. I highly recommend the tc2.0III while the previous model tc2.0II was not worth using.
At the very least with your D4 the autofocus should be about the same between using the 1.7 and the 2.0.
Thanks Jim, hard to find people who have the same setup as I do. Yes for birds in flight the tc 1.4EII is the way to go. I have tried using the tc 1.7EII without much success for birds in flight. The tc 1.7EII seems to need good light with contrast or it fails to produce good focusing. The tc 2.0EIII is suppose to have better optics.
I have a lot of confidence using the tc 1.4EII for fast and accurate focusing, good for bif.
I have all four Nikkor TC's and the TC-20E III is optically as good as the TC-17E II. As for AF speed on a D3s combined with a 400mm f/2.8 they are close but the TC-17E II is slightly faster. Don't even consider the TC-20E II.
Jim, I got to try out the tc 2.0EIII using my Nikon 500mm f4.0 vr lens in bright sunlight. I then mounted my tc 1.7EII and took the same type of images with it. I have found that the tc 2.0EIII is slower, even a little sluggesh. The tc 1.7EII is faster. The tc 1.7EII is no ball of fire for speed of focus. I then put on my tc 1.4EII and it focus's almost as fast as the native lens. I love my 1.4, but wish it reached out more than 700mm, but it is good for bif. I think I am going to pass on the tc 2.0EIII, the two converters I have are enough I think. I am sure the tc 2.0EIII would work a lot faster on an f2.8 lens versus my f4.0 lens.
I've done some testing of the 600 f/4 Vr with all the teleconverters on the D800E. The 1.4 shows a bit of drop off but is usable. The 1.7 requires very good light and definitely gives up some sharpness. The 2.0 is very good for a 2.0 - it roughly matches the 1.7 for sharpness, but you still have the loss of light. I find the 2.0 to be much better with close subjects - small birds - than distant subjects.
I have the 1.4 and 1.7 TC's. From everything that I have read the most recent version of 2.0 is superior to the 1.7. I also understand that the autofocus is a tad slower on the 2.0 as compared to the other two. I will soon be getting the 2.0
As I stated for me using a f4.0 lens (Nikon 500mm) the tc 1.7EII seemed to focus quite a bit faster than the tc 2.0EIII. I suppose for static subjects the tc 2.0EIII would be ok. Even the tc 1.7EII is not very good for bif, but the tc 1.4EII is the way to go for bif. I did not buy the tc 2.0EIII.

Thanks for sharing Larry, Eric, Jim, Brian, Marty and Rudy! Good thread for me to read as I am in exact same boat as Larry and therefore probably same conclusion and for same reasons (probably just stick with my TC14E and TC17E for my 500 VR).
I do love my TC17E for perched birds and it gets a ton of that work where it is my preferred TC, but even with my newer cameras I don't love the TC17E on my f/4 lens for BIF due to speed of initial acquisition. Great to hear other's experience.
