I believe I have the same focal reducer yet I've found most of the APSC lenses I've tried have not covered the sensor. The different sensor ratio probably being responsible.

It should be noted that 'APSC' is used for several different crop factors 1.5x (most of my APSC kit) 1.6x (Canon) & 1.7x (older Sigma)

I've only tried a few 1.5x with the reducer all of which clearly showed the inside of the hood.

Zero vignette with this lens and this focal reduction adapter on my M4/3 camera image.

I am off shortly to try and set the FR adapter to register infinity.

It may be that I tested mine with UWA/fisheye lenses that where close to the minimum coverage needed for APSC. There are quite a few 'APSC' lenses that can actually cover FF.
