this is great!
i did a review of some of the same lenses on a classic A7 with the kolari UT sensor mod here
I've been shooting with that camera and a variety of m-glass ever since. i'm curious to see how the different mods compare as i will be needing a camera upgrade soon.
Thank you for your review, I read it a lot after I have done the thin filter mod since 2015...
I did different types of NKIR thin mod before:
2015, A7R2 A7R2 + NKIR v1= 0.7+0.7=1.4mm , v1 filter AWB tends to be too red...
2017, A7R2 A7R2 + NKIR v2+ Extreme thin mod (Remove Cover Glass) = 0.85+0=0.85, V2+ filter AWB better than v1 filter, but AWB still a little bid red...
2018-2020, A7R3/ M3 +NKIR v3 Extreme thin mod 0.75+0= 0.75, V3 filter tend to be more similar to Sony Org, after fine-tune AWB B0.5, G0.2, it much better...In a normal situation, there is no need to have URIR cut filter, but on an extremely Sunny day, Using a UVIR cut filter will correct the AWB, like Leica M8/M8.2...
It seems that Kolari ultra-thin mod, the thin filter tend to be too red...
The advantage of removing cover glass is that you can use a 0.7-0.85mm filter to correct the AWB easily and more stable...
NKIR thin mod, does have V4 thin filter mod, the thin filter ready have UVIR cut coating, but the AWB tends to be more green, not so stable than v3 filter, so I still remain to have v3+ filter...
After 6 years with different thin filter mod, my experience is that , what thin mod depends on what lenses you use most, if you are just using GR21/3.5LTM, ZMC21/4.5... Standard thin mod 1.4mm or Nikon Z7 ORG 1.67mm is good enough for edge improvement...Using a 0.7-0.85mm thin filter will have a better AWB correction or stable color performance...
If you want to use Contax G16, Minolta G-Rokkor 28mm F3.5 LTM, remove cover glass (0.75+0)or using Kolari thin mod (0.2+0.7)is the only way...24-30mp is much more better than 42mp/61mp...

For Z7 ORG : 0.5+0.47+0.7 = 1.67mm
For A7R3 ORG : 1.78+0.7 = 2.48mm
For A7R3 NKIR Standard thin mod = 0.75+0.7=1.45mm
For A7R3 NKIR Extreme thin Mod (Remove Cover Glass) = 0.75+0 = 0.75mm
total 1.7mm NKIR v3+ thin filter mod

AS coating

full spectrum conversion

NKIR B03/B05/Y03 this like Kolari Vision IR , but NKIR was released two years before Kolari.

M9 change thin filter
