I have used the Kenko Pro 300 1.4x successfully with my Sigma 17-50 mm 2.8 as well as my Canon 70-200 mm f/4. While Kenko does not address Sigma or Tamron lenses, I can assure everyone that unlike the Canon 1.4x it works flawlessly, including autofocus, with not only this Sigma zoom but also my Tamron 10-24 mm wide angle. This ability to use a wider field of lenses is a significant advantage of the Kenko TC's versus the Canon.
I recently shot a lot of images in Death Valley National Park with the Kenko 1.4x on my Sigma 17-50 mm, many from a moving small bus, and they came out great.

I have the Kenko Pro 300 AF 1.4x and it works on all of my lenses including the Sigma 150-500mm. I like it.

Good to know! Although I didn't list it I use the Sigma 17-50 on my D5300 most of the time. I didn't list it because I have a replacement 55-300 on its way and will use it for more reach when I don't want to lug the 200-500.
(I gave my 55-300 to my daughter-in-law when I got my 28-300. I realized after that I preferred the 55-300 on my D5300 for the light weight. My daughter-in-law won't give it back: calls me an "Indian Giver". Found a refurb on the Nikon sale for $149 so bought it in the interest of peace in the valley.)

Thanks!
So that makes the Teleplus also OK with the lenses I have but doesn't help answer the question as to the differences. Undoes the tentative decision above: back to square 1.

According to what I read the Teleplus MC4 series are for the older AF D lenses and not the newer lenses with the focus motor in them leading me to believe that the AF-S lenses will be manual focus only.
Per the table it is good with AF-S lenses.
Looks like both converters can have autofocus difficulty when min f-stop of lens plus one rises above 5.6 on D5300 and 8 on the D800. Probably worse in low light. Might need to live with that. Ok for the occassional use I intend.

The Pro has 5 elements vs 4 for the MC4, and the elements are bigger in the Pro. Although, I have seen a formal testing showing the MC4 to have better resolution with a Canon 70-200 zoom.
Gee, Kenko USA says the Pro 300 has 7 elements in 4 groups.
Are you saying they don't know their own product?

Thanks for a good link.
The difference isn't jumping out at me. Although one says it is for prime lenses it goes on to say it is good for zooms above 50mm.
I'll print and do a detailed compare of the writeups and specs to see if that tells me the difference.
Seems like there should be a significant difference to justify two products for the same function.

Kenko says that the Pro 300 line uses higher grade glass, coatings etc. And in the specs the weight of the Pro 300 1.4x is given as 5.3 oz while the MC4 1.4x is given as 3.9 oz.
Different design and Pro 300 is higher grade materials and more solidly built. Compared to the Brand name extenders the Pro 300 line are inexpensive. I own 3 extenders, Pro 300 1.4x & 2.0x and the Canon 1.4X III. The Canon goes on my 100-400L, the Kenkos are for everything else. I have found that the Kenko 1.4X and my Tamron 180 macro give great results, not as high a resolution as the macro by itself, but higher than most other lenses. On my 7DII that gives the AOV of a 403 mm and works nicely for humming birds at the feeder or insects on flowers. I haven't really tried the Tamron with the 2.0X yet, that one I got when I was playing with moon shots.

They aren't, I just read the specs on both the Tamron and Kenko sites.
Here is Tamron:
