A7 with Kenko 2X and Sony 55-300mm


I have been trying to do some photos with my A7 my just arrived Kenko 2x Teleplus MC7 and my DT 4,5-5,6/55-300mm SAM lens.

To my surprise is: The auto focus works, even it is stated it only works with max F4,0 lenses.

Even bigger surprise is that the lens is for APS-C sensor, but I have no vignette.

The cropped photo have been retouched. The non cropped have only had auto expose in Lightroom.

Any who can explain why I can use an APS-C sensot on a FF with out any cropping?
