I have found this to be an excellent compromise between a 1.4 and a 2.0 TC. I didn't think that the 1.4 added enough focal length to be worth it, despite the excellent image quality. The 2.0s provide more focal length, but cost substantially in both light and sharpness.

Attached to the Nikon 105mm f/2.8 G ED VR macro lens, I get super sharp images without loss of detail. When taking the shot of the first attached image, my hands are a bit shaky, but the VR of the 105mm lens was able to recover and gave me a blur free image.

After reading the reviews, and recognizing there is little cost between the 1.4 and the 1.7x, I decided to get the 1.7 for my 70-200. My goal was primarily taking pictures of birds, and I knew I had to get closer to get better shots than I was getting.

I use this Teleconverter it mainly on my AF-S Nikkor 300mm f/4 PF ED VR and no noticeable drop of image quality. VR working very well. AF works fine, maybe a tiny bit slower. Compact light and fast. SJ

I would rate the 1.4TC as the only TC that will yield excellent results across the board. The 1.7 is a good compromise, but dont expect it to yield tack-sharp results on every lens. You need to stop many lenses down at least two stops when using this TC to achieve max sharpness.

    Good reach, works flawlessly with top-quality glass

    Not as sharp as 1.4TC

Very nice accessory for a relatively fast lens (2.8 or less). Somewhat expensive, but excellent optical clarity. A great way to nearly double your reach with only a small penality in light loss.

  • +

    The converter is very easy to use, and with Nikon's modern lenses it enables all functions. Optics are excellent, and very little is lost in sharpness. The 1.7 is a very nice middle ground between the 1.4 and the 2.0. Many will find that this lens is the only one they will need.

  • -

    The converter is expensive, and a little inconvenient if you are in a hurry.

Simple, easy to use. Really appreciate it with my 500mm Nikkor lens.

When coupled with the AF-S Nikkor 300mm f4E PF ED VR lens on the Nikon D500, the lens is equivalent to a 765mm f7 or so lens. Sharpness is very good across the frame and focus is relative fast in decent light.

I got this converter mainly for use with my Nikon AF-S DX 70-200mm 2.8 FL ED VR zoom...for people shots and wildlife. Ive only done a few simple resolution tests with it . I had to make some minor AutoFocus Fine Tune adjustments, in camera, with my Nikon 7100.

Great images with this teleconverter. Just got back from a safari trip to Tanzania where I used this along with my 70-200 Nikon lens. It did a great job of bringing the animals in really close and with no noticeable drop in quality . Highly recommended.
