Very briefly compared! Kenko DGX 300 Pro / Canon III

I save just once specifications and pack size. I got me the Canon 1.4 III converter made as fourth attempt to get with little weight gain more focal length. Should this fail, I would have resorted to another Canon L.

To use it comes with me to the 70-200 / 4L IS.

For Comparison:

The Kenko Teleplus 1.5 DG made only at extremely bright light for halfway useful results and the Exif data were wrong.

The Kenko DGX 300 Pro and Canon 1.4 II attended in bright light and stand for decent results that are much better than the 1,5er in quality. But still have (for images without converter) on both visible differences. Otherwise, the two were pretty much on the same.

But the mentioned here Canon 1.4 III me to skin. Eigendlich I did not want to spend so much money for a converter, but it's worth it, in my view, in any case. I see no appreciable difference, whether with or without converter .. It may be that is slightly slower, the combination, but with the combination I do not shoot from the hip yes.
So far, I had assumed that the DGX 300 would ran close to the best converter for Canon, but if the Canon 1.4 III stands for 100%, I saw the Kenko at most 75%.
I've honestly not expecting something that's technically possible. I'd buy it in there again !!! Unlike the first three converters which I had hardly ever used, I take the Canon 1.4 III happy with and used it well.
