Pick the M9 IR cut....

I'm testing a prototype ultra-thin IR cut for possible use on Sony A7 for M wides. We know what happens when you take the standard M9 S8612 IR cut down from .8mm to .5mm (as in M8). Magenta Blacks.

 

This a new glass technology, far thinner than the M8.

 

Can you see IR problem? Can you tell M9 from Sony?

Lenses are TE 90 in the first two, and 35 Skopar in the second. Forgive purple snow, it was sundown.

 

Tips for rigorous IR leak testing?

Tips for rigorous IR leak testing?

Maybe try some indoor shots with low light situation, not with the sun shining through the windows like your shots. I think those conditions would be very hard for using my M8 without IR cut filter.
