Hello all! Does anyone have either the TC-17E, TC-20E II, or TC-20E III that they use with the 70-200 VR2 lens? I would like to get a 20, but I have heard some people have had issues with it. Any experience with this would be great! Thanks :)
Looking for a TC for the 70-200 VRII(20 posts) (15 voices)
Most people are more then happy with TC-17E, it seams to be the best balance between then gain, aperture loss and IQ.
I just purchased the 20E III for my 70-200 and just love it.... no apparent IQ loss with the TC and the double focal lenght is terrific. My only sorrow is that it doesn't -ork with some of my other Nikon lenses but I did get it for the 70-200 and couldn't be happier....bob
Yeah, that is kind of where I find myself to be...right between the two. I am kind of leaning more towards the 17...but who knows. :)
Bob, how is the auto focus at various apertures? I have been considering the tc20e-III also for my 70-200vr.
I have both TC20II and TC17II on my 70-200 and both perform very well, although I prefer the TC17II as it offers better f-stop, or should I rather say - it's fully usable when You shot wide open with it. With TC20II You have to close at least one f-stop.
the TC 17 makes the 70-200 effectively what? 140-340 and a flat f/4.8?
I'm considering getting the TC17 as well. . .wasn't one of them recently re-designed for the 70-200 VR2?
TC17 will make Your 70-200 effectively 119-340/4.8, and it wasn't redesigned for the new one, only the TC20III was
maybe I'll just rent one a TC 1.7 or 2.0 to try'em out before I plunk it down.
Was hoping a 'redo' of the TC 1.4 would've been out by now. . .
i've been using TC-20E III for a while and can say that it's amazing. there's no IQ losswhich is really important.
I am in the same boat. Looking to find the right TC for my 70 - 200 VR2 2.8. I have a D90. The combo makes very sharp pics as is.
I have the TC-17E and love it. I used the older 2x I & II and I thought they worked well and never saw any issues and everyone seems to love the III.
The only thing with 1.7 and much more so with the 2.0 converters is when light drops and you are stopped down, AF starts to hunt and hand shake comes into play quickly. No big surprise, but many claim to have soft TCs when actually they are trying to handhold below 1/300 & 1/450 on DX and think every image will be sharp.
Another vote for the TC-20E III but if posible, for best IQ, stop down to f8
I do not have a TC-17 to compare and I try to avoid using the TC-20E III as much as possible but there are cases when 200 mm is just not enough and adding a 7 pound 200-400 mm to my already overweight setup is not an option. In those cases, being able to go 400 mm for a little weight and portability cost becomes a true savior and I rarely endup shooting at or below 340 mm, to the contrary, I often whish to be able to go beyond 400mm.
I also use the TC-20 a lot with the 105mm macro.
hmmm interesting thoughts... I was looking more for the "median" of the lens i guess
Well my experince with the TC-17 is I have one, I rented the TC-20 III once.
This was not a fair test but here is my set up and results:
Camera 1: D700, TC-17II, 70-200mm VR2
Camera 2: D7000, TC-20III, 400mm VR (2)-I think this is the only 400mm with VR
The D700 locked on to the subject right away, the D7000 hunted for a moment. The cameras were less than 10 ft apart. This was done at the same time of day, aprox 8 am in June, location FL coast, extreme overcast.
I had not used either the D7000 or the 400mm before that point so a learning curve occurred. I have used the D7000 and the 400mm/TC-17 combo since then and still think the TC-20 III would hunt more than my TC-17 does in low light but with either I dont really see a difference in quality so long as you have good technique.
If I ever have the need to use the TC-20 III again I will test it a little better, but at the moment I was still learning other things so a TC wasn't my primary problem.
you should have tested the lens combos on the same camera, for testing purposes.
both combinations on the D700 and then on the D7000 for camera test puroses and lens test.
test of the lenses on different cameras are not valid for lens evaluations.
also, on the D7000 a 400mm f2.8 X TC20 will give you 800mm @ 5.6 x 1.5 =1200mm @5.6
and you expect zippy AF performance?
Well I know that, but I was not worried about testing a TC. I was more worried about learning a new camera that I had not used before. The DX crop shouldn't affect AF performance, its just a bonus if your looking for more reach. I do not expect zippy but just telling what I found, I just tried to help.
So far the need for a TC-20 III has not come up again for me to test one out. If I ever do again I will test all aspects.
I will do a FF and DX test with the 70-200 and 400mm with both TC's along with some day and night testing on both. Both would have the same subject(s), one close and one distant, the only draw back is a possible sunrise/sunset shot may not have the exact same lighting if I am not fast enough changing out gear.

I had the same experience.
I'm not sure what the technical reasons are, but TC's do seem to perform a bit slower on DX than with FX. Not much though. I notice it, but it has to be a very fast moving object like birds, animals, etc. It could just be tracking an object at (w TC1.7 & 70-200mm -bright light- f8 @1/1000) 300 vs 510 is going to be more difficult at the 510 that DX creates with a TC1.7. The TC20 seemed much slower and that is why I choose the 1.7 as well.
I spoke to others that experienced that with DX as well but that was before the new AF motor/design in the D7000 which seems to be about the same as the D300/D700 (shared AF design) and much better than the D200, D5xxx series. I also thought the D700 was faster compared to the D300 even though they shared the same AF design.
Either way, I think there it says something more about the AF designs than the TCs performance or particular glass you attach it too.

I have no idea what is meant by that statement.
I just shot my first serious event this past weekend with my 70-200 VR2 and the TC2iii.
Here is one pic of it in action. I did not notice any degradation of image quality, even wide open at f/5.6. Though I still stopped down some to f/7.1 for some shots as I had enough light. I love the combo.
The rest of the photos are in a gallery at my site.
