Recently bought a used previous generation of Nikon's 70-200 VR and the combo with the 1.7x was NOT as good as my 20 year old 300 f4 ED prime. Seller's remorse set in! I just traded for the new 7-200 VRII and they work extremely well together!

Have used this teleconverter extensively with my Nikon 300mm f/2.8 and my Nikon 70-200mm f/2.8, with no issues in very rugged conditions. It is my go to teleconverter for my 300mm lens when my 600mm is not with me. Never been disappointed.

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 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.
