Summary: I borrowed a Canon 2X extender for a test with my 400mm lens on a T3i. It worked well, but it negated autofocus. After reading several reviews I decided to try the Kenko 1.4X as an inexpensive alternative that would preserve the autofocus. My first impressions are very good.
Summary: I'll admit I'm not a huge fan of using TC's generally speaking but my opinion has been based on shooting film from decades ago. I wondered if maybe technology had caught up and if today's tele-converters were better than the ones I remembered.
Best 3rd party TC in the world. Works extremely well when others will not.

Summary: Flawless performance on my Sigma 500mm f4.5 EX APO DG HSM and 1D Mark IV when the Canon and Sigma TCs will not even allow AF. Perfect AF and 99% of the image quality you'd get without a TC but with 700mm f6.3 reach. Plus it is roughly 1/3-1/4 the cost of the Canons and Sigmas! Highly recommended.
Summary: I had little expectations to use a converter for increased reach, assuming that image quality will degrade. Instead, I got it for the changed perspective of a longer focal length (compression) and shallower DOF. Optically, it is as good as one could expect from a teleconverter.
Summary: This teleconverter is a great option for those Nikon owners who have a lens that is not compatible with the Nikon teleconverters. This one worked perfectly with my 55-300mm Nikkor lens, but do note that it will drop you down one stop on your aperture.
Summary: This is one of the best camera gadgets I have ever used. I've had the DGX model since it was first introduced, and it has resided on my Nikon 70-300 VR lens since then. It autofocuses almost perfectly on my Nikon D7100 with that lens and also with my Nikon 18-140 all the way out, at f/5.6.
Pros: Works perfectly; excellent optics; autofocuses well; light and easy to use
Summary: Hubby's review: I have a few lenses that benefit more on a crop sensor camera, like the Tamron 10-24mm f/3.5-4.5, than on a full frame camera. With this extender, that lens now becomes 14-33mm on the full frame.
Summary: Very Impressive. The only negative is I waited too long before buying this. Allows for sharp, clean photos. I used some with obvious image degradation. That is not the case here. The hit on quality is barely noticeable if at all in most situations.
Summary: ...as long as one knows that, I think one can't help but be happy with this item. The results are more than adequate in my opinion....especially when compared to price of the Nikon version of the same thing and the alternative of buying a lense of similar overall focal length as I get when I combine...
