This teleconverter is extremely sharp and gets the job done. Luckily I did have a lens that was compatible with it. It's my own fault for not doing slightly more research to find that some nikon lenses are not compatible with this device. Be sure to check before purchasing.

Make sure you carefully read the list of lenses that this works with on the copy of the manual available at this site. I have three very common Nikkon lenses , two of them zoom lenses, and this does not fit any of them.

The only people who have had a problem with this product have not paired it with the right lenses. ((( This TC Converter is designed for fast f/2.8 lenses. ))) I have two Nikon cameras (D810 and D500) and this 2x TC III doubles my reach and keeps the quality extremely high.

It really makes my 70-200mm lens longer and heavier. But I wanted something with more reach and this teleconverter allows me to do that.

great extra in your camera bag! well built!

"After all the positive reviews I read I grabbed this to use with my 70-200VR2. I wasn't happy at all with the results, I got very few keepers when using it, often times I had to choose to keep the picture that was least bad of a set.

An exceptional camera tool. As with all Nikon equipment, the optics are superior. The teleconverter adds weight but the pictures it provides are worth it.

Great optics

Weight

While it's a shame that picture and sound quality haven't been upgraded, the iPhone 13 was great in these regards and the iPhone 14 is, too Excellent display Admirable headphone performance Solid build quality No upgrades to picture or sound Familiar design Notch is still present

Apple's latest non-Pro iPhone is superb - it's just that it's strikingly similar to last year's effort.

Still an incredible smartphone, Brilliant battery life gets a bit better, Excellent camera system gets a bit better

Last year’s Pro hardware, Wireless charging slow by modern standards, No USB-C; it’s now well overdue
