Has anyone had any experience with the Nikon 1.4 telefonverter iii and the 70-200 2.8 lens? Is the 1.7 or 2.0 better than the 1.4?

Here - http://www.lensrentals.com/blog/2013/03/the-requested-80-400-af-s-vs-70-200-vr-ii-and-2x-comparison - is what you will want to read - hope it helps somewhat ! The 1.4X will render the best resolution and AF speed.

Depends what you want from the converter. The TC2.0 111 works very well in good light, giving a maximum 400mm F5.6. The 1.7 converter is still the old 'mark 2' and soft. The 1.4 makes the lens an F4 with a 280mm maximum.

With both tc's you loose some sharpness, though the new 2.0 is very good in that respect provided you have a fast speed set, greater than 1/200th for best results.

AF suffers in low light conditions; the lens will tend to seek quite a lot and be slower to set AF. With the 2.0 this is more pronounced.

I cannot personally see the point of using the 1.4 on a 70-200 lens; for pretty much the same money as the TC costs you can pick up a 70-300 4-5.6 which will serve better as AF speed and seek are better plus you get better sharpness.

That is true. I can buy the 70-300, but I travel a lot and do not want to travel with a lot of gear.

It works great, with hardly any image or performance degradation. The other two are good too, but with each increment, you will reduce your IQ and the focus will get slower and less accurate.

Because you have a shorter zoom lens and not a long prime, IMHO you will be better served ( and cheaper) using a Tamron SP series TC or the Kenko Pro series.

With the Nikon 70-200 the Nikon TC's work better than any of the other manufacturers though they do cost significantly more.

What do you base your statement on ?? Please share....

About ten years of using various combinations of teleconverters with zoom lenses. Checking performance of Nikon lenses with Nikon TC's against Kenko - which seem to be the best of the third party manufacturers and Sigma it was difficult to understand why their images were consistently softer and yet when using zooms like the Sigma 150-500 the non Nikon seemed to work OK.

If I understand the situation correctly the AF responds more quickly and is sharper with the Nikon TC combined with the Nikon zoom. You can see this if you look at the images at 100% particularly in less than perfect light.

It is also perhaps the case that the Nikon TC's particularly the latest generation - TC1.4 v111 and 2.0 v111 - have some very good optics, miles ahead of the previous versions.

You do realize that Nikon, like Canon, optimizes their TC's for prime lenses 300mm and longer ? (which is one reason why they have a protrusion going up into the lens) Shorter zooms are a different animal - which is where the 3rd parties are optimised. Go here - http://www.traumflieger.de/objektivtest/open_test/telekonverter/overview.php - to see a Kenko out-performing a Canon TC on a 70-200 zoom ( Translate from German)

Yes. Personally I mainly use the 2.0 111 on the 300mm F2.8 when I can't get my 600mm to site, such as when flying. And thanks for the link, I had not seen that before.

Nikon do not optimise for the 300mm and above - they apparently optimise for their fast prime range above 200mm, - the TC2.0 111 works very well with the F2 200mm I'm told.

I have tried Canon teleconverters normally with primes on a 1DX - I found the results disappointing in less than perfect light though this may be down to a lack of perseverance on my part. As the Nikon 2.0 / 600mm combination works so well (and all the other primes tried) I usually go for Nikon when a situation arises that calls for a TC.

I'm not criticising the likes of Kenko and Sigma TC's; rather pointing out that you get what you pay for and a Nikon TC does outperform these on a like for like comparison including the 70-200.
