Decent optics, but not for every lens...

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. Yes, color fringing, most visible in high contrast transitions, will increase. This is expected as no converter will correct flaws of the lens, only enhance them.
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. It is really only good for bright light situations because it hesitates on autofocus otherwise. Worth it for me!
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. With my 28-105D, autofocus is always perfect. Only with low contrast shots, e.g.
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. On the full frame camera, the vignetting was really thick on the sides at 10mm and faded away at 13mm. Now there's no vignetting at any focal length. Also, this allows me to shoot with a newer Canon camera than my 40D, which has a crop sensor.
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 my Nikon D7000 (DX format...1.5x) with this teleconverter (1.4x) and my Nikon 70-300 f/4.5-5.6 AF-S ED.
Summary: Words very well, could not compare with Canon, but much cheaper and good mate for 70-200 L lens. Resolution in center is same at f/5.6 Slight amplification of edge sharpness. Will amplify distortion of any lens, but nice lenses work well. Sturdy connector, autofocus works for D20.
Seems like a great alternative to the much more expensive Canon.

Summary: I bought this TC because, like most wildlife shooters, you can never have enough reach. This TC is just a fraction of the Canon one. I can't give a direct comparison because I have not used the Canon one. But this one seems very well made for the money. I have used it with a Sigma 17-50mm F2.8 and a Camon 70-300L attached to my 70D. Technically, the AF isn't "supposed to" work with the 300 at max zoom (extended to 420mm F8).
