Returning it. Did not auto focus with D800 and Tamron 18-400 lens. Manual focus ring is too loose on that lens for my taste to use and image quality was poor on test shots.

2x teleconverter preserved automatic metering and focus on my D7000. Image quality was respectable. I used it to take pictures of sunspots with a sun filter. Saw a few. Instructions should emphasize that you turn the caps clockwise to remove them. I struggled a bit.

Sharp focus! Used this with my Nikkor 1000mm f/11 reflex lens for the last Eclipse. Enable me to extend out to 2000mm. Resulting photos were sharp, no flare, no aberrations. I was really surprised. All autofocus features worked are expected. Robert E Clark, Santa Monica, CA., 2017.

I bought this several months ago and have used it in various settings. It works well as a 2x teleconverter, but I give it 2 stars because the autofocus does not lock well at all. I used it to photograph the eclipse with a 400mm lens and I didn't have any problems since I was in manual focus.

A bit slow to focus, but otherwise a good teleconverter.

Good for fast lenses only. Autofocus does not work on 70-300 f/4.5-6.3 AF-P lens.

Currently in use between a Nikon 500mm reflex lens and a Nikon D80 body. Modest components in today's product lines. And I had read a review that this was best as a paperweight. I am happy to report, it works great. Not Nikon optics, but a bargain and the quality at least matches that of my gear.

Nice for the purpose and price. Not quite Nikon? but Nikon doesn't make a converter for my D5600? Best on the market from what I've read. My zoom doesn't match up to my P900 2000mm superzoom bridge camera but not a fair comparison from 300mm optical lens to 2x teleconverter 600mm optical.

difficulty with obtaining any focus with my Nikon D7100 camera and various lenses. returned the item.
