In summery, this an excellent product.Read more ›
The Kenko fit just fine, and performed very well. It is a very high quality optic, and I have no issues with it at all. Mounted on the 70-300 DO IS lens, it transformed it into a 98-420 mm lens with a max aperture of f/8 at the long end. Mounted on both of my 30D bodies, AF was fully functional at every focal length. That was a bonus that I expected to have to live without, as AF can be spotty at best at f/8.
It works fine, and the captured images are very fine. I like this TC. I also tested it against my Canon 1.4 extender on my EF 70-200 f/2.8 IS L lens, and found little to choose from between the two. They can also be stacked on the 70-200 f/2.8 lens (not all lenses, as the stack will only work if the Canon extender fits to the lens, and the Kenko fits to the body), and the image quality is as good as the Canon 2x extender by itself. You can see many possibilities here....
The Kenko is very well built, but it isn't really cheap. It is on par with the Canon in performance, and fits more Canon lenses than the Canon extender, but only the Canon extenders are weather resistant. They incorporate an O ring that seals to 1D series bodies, and to weatherproof L lenses. If that isn't an issue for you, the Kenko is a great product.
I'll buy another similar Kenlo product without hesitation. By the way, the Kenko and the Tamron extenders are identical except for branding. As best as I can tell, they are both built by Hoya/Kenko, so I went with the Kenko brand. I have handled both though, and they are the same product.
On the other, the problem that I have using this Kenko Teleplus PRO 300 DG AF 1.4x Teleconverter is that the camera cannot register automatically in the EXIF data the correct focal length and aperture setting of the aforementioned lenses. However, it is understood that using such TC 1.4x like this a one f/stop loss and 1.4x increase in focal length of the lens being used are expected. But on the other after manually adjusting the aperture setting which is required to get sharper images, the camera can identify now and register the adjusted aperture setting as reflected in the later EXIF data. This is only a minor problem which has nothing to do with image quality of our taken pictures and which can be ignored.
As of the moment, I am happy with this Kenko Teleplus PRO 300 DG AF 1.4x Teleconverter which is giving me an added range for my lenses without suffering the loss of image quality of my pictures.
I highly recommend this TC for your added range.
