Done some handheld testing with my converted Minolta MD I 200mm 4.0 and the Canon 55-250 with and without the Kenko. On an A7RII camera. with Metabones IV adapter.

Near the center, 400 and 300% view in Capture One

Near the right bottom edge , 400 and 300% view in Capture One.

I shot a church tower at 500 meters with the Kenko and that showed a good image but I am not happy with the Kenko results here. The Canon on its own is better than expected so I am not disappointed.

Given that it looks better in the center and worse at the edges, the converter seems to be (mostly) at fault. Certainly, I did see a wide range of performance differences between various converters....

My guess as well.  David Kennard used another Kenko for APS lenses that was not better with this lens and an A7RII.
