Fuji and Nikon Lenses suitability for IR and UV Photography Test

A test of a few different Fuji X mount and Nikon lenses, looking at their suitability for infrared and ultraviolet photography. I look at whether each lens has an infrared hotspot, how much ultraviolet light the lens passes, and how much focus shift the lens exhibits in IR and UV.
The written version of this video can be found here: www.davidkennar...
Good resources for how well Fuji lenses work in infrared are:

and:
kolarivision.co... (scroll down to find the Fuji lens section).
Lenses tested in the video are:
80mm f/5.6 EL-Nikkor
Fuji 50-230mm at 50mm
