First Sighting: A7rii Thin filter in action

Well that is pretty clear that v4 of the Kolari mod does not play well with that lens.
Yes, looks just as bad as a M wide on the stock camera
Shows just how much the lenses must be tweaked to work with the many layers of glass over the stock sensor.
I think Illija is calling this version the "ultra-thin" (UT). V4 may get confusing as 1-3 are standard thickness IR cuts, and Kolari may try another of that thickness in the future, like the STC. Would be nice to have a short designation which makes it clear which is the new IR technology. My samples are designated UT. Can we use that so readers are not confused? There may actually be more UT versions, also.

The UT is fundamentally different in manufacture, and may present the photographer with equally different IR and WB issues. It is completely new, and this is the first time ever on any FF camera or large sensor camera. Not just another "version" like S8612 vs BG55. Another "thing", which may be of interest to others in the future, for reasons we don't know here.
