The difference is kind of subtle but it is there. The T6.7 image produces a smoother yet defined bokeh in terms of the shape of the OOF objects.

**Note: apparently the camera cannot display "f6.7", it says f6.3 on the EXIF. When you look at the shutter speed on later images you can tell the exp value is different from the real f6.3 used with the regular aperture ring.
