Works great with the Nikon 70-300mm

Ummm ... it's not exactly true that this works only on "professional" cameras. It'll work on any camera that matches the mount (Canon or Nikon) and any fully compatible lenses. But it's also true that ANY teleconverter also has a light loss, which is equal to the teleconversion gain. So, since this is a 2x teleconverter, you will generally lose 2 stops of light to "pay" for the "gain" of 2x mm in focal length. So, if one has an 18-300mm lens which stops down to f/5.6 at the long end, this addition will force another two stops down to f/11. Similarly, if the lens ordinarily opens up to f/4 at the 18mm end, this teleconverter will convert the focal length to 36mm, but at the same time stop the aperture down to f/8. The "speed" of the lens will go down two stops in each case. Hope this helps anybody else who is confused. That said, I agree that customers of the Adorama site cannot be expected to know all this, so they should have mentioned the light loss factor. As it stands, the item description makes it sound like there is a focal length gain without any kind of loss! Caveat: The manufacturers state that this converter will only work with "genuine" lenses, by which I assume they mean lenses by the same maker as the mount types, i.e., Canon, Nikon, etc.,) and is not guaranteed to work with other lenses.

Adorama neglected to say this product only is for a professional-grade digital camera. In order to be able to capture birds on the fly or wildlife moving along, one must be able to set focus automatically. This product requires an aperture of 3.5 in order to use auto focus. My camera stops at 7.1, with this product attached, requiring manual focus, which is not possible when a bird is flying overhead. This product came highly recommended by a professional photographer, so I will have to assume it is a great product with the proper camera. Mine is a Canon EOS Rebel SL2, with Sigma 18-300 lens.

Teleconverter works very well; the adjustments for f-stop loss are a little tricky to get used to, but overall it does a fantastic job and for a good price! Beats a new lens if you're in a pinch.

Like the price and for not being a Nikon product it works really good. The reason I gave it a 4 star it's because it's not too sturdy. Hopefully I will make use of it for a long time.

Since Nikon does not have a teleconverter that will auto focus with my Nikon 80-200mm f2.8 AF Nikkor lens, I had to go with a third party teleconverter to accomplish the task. After going through many reviews I took the chance and ordered the Kenko 1.4x Teleplus HD Pro from Adorama. This is a high quality product that works very well and auto focus is quick and the lens only looses one stop of light. The sharpness is still very good with the extended range that is acquired by the 1.4x crop. I also tried it out on my 70-300 f4.5-5.6 vr lens with acceptable quality in daylight, although not pro quality as you would get from a prime lens.

I am using with a tamron 150-600mm zoom lens. G1. Have to use manual focus. Pictures are great at 600mm. Use a monopod. No problems.
