<<<Is this what you mean by "Stack"

The glass in front of the sensor--UV filters etc.   WA RF lenses with short 
exit pupil distances at wide apertures are very degraded in corners.  One can 
get the Sonnie cam modified by Kolari if committed to use such lenses  but have 
to be prepared for more complex work  flow with color issues. Roger had 3 good 
articles on sensor stack  effects:

BTW the zony 55/1.8 is quite nice and I rented it as a trial for Bhutan. More 
CA than expected for the price.  I did have the OMZ 50/1.4 with me too. 
Here is one shot with the 55 at f8:

Watch the stack,  Mike
