As promised here is the hot spot test at 25mm (middle) and 45mm (telephoto). And basically the results are worse than before!
Kolari Vision 850nm @25mm
Kenko R72 (720nm) @25mm
LifePixel Super Blue IR @25mm
Kolari Vision 850nm @45mm
Kenko R72 (720nm) @45mm
LifePixel Super Blue IR @45mm
Conclusion
As you can see the results are worse the higher the nm and the aperture. I would only recommend shooting this lens wide open and at lower apertures. Thanks for looking.
