Nikon TC-17E II 1.7x Teleconverter for AF-S USA

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

Great telelconverter. I mainly used Nikon's 1.4x teleconverter at various newspapers before taking the plunge and buying my own. Read great reviews and so far so good. Only negative is that you're stuck at f/4 which makes it tricky for indoor sports, or weddings in large churches.
But I shot at a college football game with it on my 70-200 V1 and had excellent results. Though I always feel silly next to the other guys with the big glass.
Good for the price though!

Use for Nature photography particularly wildlife. Like that it is always available without the weight, bulk or cost of a larger lens particularly when hiking in the back country. I am using it with the 70-200 F2.8 VR II Nikon lens and accept the f stop loss in exchange for the 70% increase magnification. This loss is about equal to using a polaroid filter. I often compensate by removing the latter to avoid the accumulative effect in low light or active critters. Seems to be fully compatible and at full power shows up as 340X in the metadata. Since I using a D300 DX camera that provides 510X. Otherwise have not found any additional downsides.

Just came back from Yellowstone National park. Used this teleconverter with NIKKOR 70-200 2.8 lens. Results were amazing. Shot animals close up with fantastic detail and sharpness.

Helps me get some more reach with my 105 VR and 70-200VR II without loss in IQ.

I bought this with the 70-200 f/2.8 VRII. My first pics were with the 1.7x TC and they were good, but not great. I love how I can get close to birds that I never could before.

I think the picture quality will improve with practice, especially with respect to focus, and getting used to the depth of field. With the 1.7x TC, the meter on my D90 reads f/4.8 when the aperature is wide open (I think because of the reduction in light? -1.5 stops). But the photos appear to still have the depth of field of the f/2.8 aperture in the lens.

I am happy with the TC, just need more practice to get the shots I really expected.

Perhaps I should give this a 4.5 rating so far, but I don't feel that I have really put it through it's paces in tough situations yet so I am being conservative. So far I have only used it on my f2.8 70-200 VRII. Is there a loss of sharpness? Sure, but not to any unacceptable level. The lens still seems to auto-focus very quickly and so far the loss of 1.5 stops has not been an issue. I am hoping that it works as well in lower light situations as I shoot a good deal of live music. I decided to get this after they put all the photogs at the sound board instead of in the pit for a show and the longest lens I had only went to 200mm. Now I can quickly and easily reach 340mm without paying thousands of dollars or carrying extra great weight.
I am confused by reviews that say attaching this extender is difficult. I guess some folks don't know how to match the dots and twist. It's quick and easy.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

Pros: It gives you the extra 1.7x so if you need it.. its the way to go.
Cons. If your using the 2.8 lens your widest opening will be at 4.8..

This wont fit in the pocket of a tight pair of jeans, so if you want to remove it while traveling you will need some sort of bag (fanny pack will work too, its not that large.)

Just what I needed to get that extra distance without having to buy another lens. For use on my 70 - 200 2.8F Nikkor telephoto - so stop loss will is not too great

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

I have been reluctant to use TCs because of their potential for softening the image. After reading the reviews though, I decided to try the 1.7 with my new 70-200mm VRII. I have been very pleased with the image quality and can highly recommend it with compatible lenses.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

Using on a 70-200 2.8 VR and the focus remains lightning fast. The loss of stops def. became hindrance in my first shoot forcing the ISO to creep up a bit past where I would like. Overall if you have to make a tradeoff for the distance I would highly recommend.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

As you would expect from Nikon it works. You loose A little light 2 f stops . On a 2.8 lenz not such a big deal on a 4.5 or higer f stop lenz you need good light or it wont work well.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

I use the 1.7 TC with the Nikon 300mm f2.8. It works well when I need just a little more magnification. Of course the maximum f stop goes to 4.76 with the TC and focus slows slightly. But that is small price to pay for the extra 210mm. Anyone using a TC of any kind should be aware there is no free lunch. There will be slight image degradation with its use. Of course the 300mm f2.8 is razor sharp even wide open so the degradation is quite small and is noticeable only with careful study of the image.

Perfect for use with the 70-200mm 2.8 VRII. Excellent design - sharp images and full use of lens.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

This TC was designed exclusively for AF-S lenses. I think this constraint helped make it a practical solution for the 1.7 magnification factor. The images are very sharp at the expense of 1 f/stop. The VRII and AF work very well .I love the product. This makes the 70-200 VRII lens a 510mm on a DX body. I would not hesitate to purchase.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

Mixed feelings with this Nikon Product.
PROS:
1. Well built.
2. Supposed to have great glass.
3. Seemless (almost not noticeable) with Nikon Lenses.

CONS:
1. Expansive Product
2. Sad that it will ONLY work with very few Nikon lenses.
3. Stranger that other manufacturers make similar products that work with far more lenses.

What's the deal here?
I stayed with Nikon, and feel that I was punished!
Now I have 100's of dollars waiting around.
Will not work with 80-200 f/2.8

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

Used with Nikkor 200 / 400 F4 IF ED II Pro Zoom.
1. Still produces very sharp results. No need to stop down.
2. Slows down AFS Auto focus on subjects with lack of decent contrast.
3. Excellent value for 680mm capability

I received the poduct last week and this weekend I went to the river to take pictures of the rowing teams on the river. I used the teleconverter with my Nikor 70-200mm. So far, it performed well. The images looked sharp.

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

I ordered the Nikon TC-17E II 1.7 Teleconverter to go with my new Nikon 300mm 2.8 lens. [...] I shot practical tests of local street traffic with and without the teleconverter. After blowing them up to 11" X 14" the shots WITH the teleconverter almost seemed sharper than the lens without the teleconverter, if that's possible. The results were very sharp. The VR and autofocus on the 300mm 2.8 worked perfectly with the teleconverter attached. Of course, you loose almost 2 stops, but for working outdoors shooting sports or wildlife, a 510mm (full frame) f4.5 lens comes in pretty handy!

Comments about Nikon TC-17E II 1.7x Teleconverter for AF-S:

Works well mounted with the 70-200 VRI.
AF is not affected by much at all.
IQ difference with or without is subjective.

I bought this tc to use on my Nikon AFS Nikkor 300mm f4 ED-IF. The 300mm lens is a very good lens but takes a certain amount of technique to get good results. Adding the tc 17e II to this lens adds to your problems. Lighting become crucial. If you have good light it will auto focus quite well. As the lighting diminishes so will the auto-focus.
I was using this tc mainly for birds. I started out with eagles from quite a ways out and it would focus quite well if you are dead on the bird. If you happen to lose focus it was hard to regain as the lens would start to hunt. This set-up is much worse with smaller birds as it just takes to long to focus as they flit around very quickly.
My rating of three stars is based on the fact that Nikon does not rate this lens to auto-focus with the tc and yet it will at times. All the electronic transfer works and the build quality is quite good. The quality of photos so far has been disappointing. I can get better results just with the 300mm lens and cropping. To be fair , the weather has been cloudy and the lighting poor for almost all the time I have had the tc.
I am going to keep this tc because I may look for a different lens in the future and will need this tc for it. Also the tc may be better in the summer with better light.

I had better add this was used on the D7000 Nikon camera body and possibly using with camera body with more advanced focus system would improve focus results.
Although this tc is quite good I was hoping for more.
