A comparative, subjective shootout of Lenses for UV Photography ... Fluorescence

So, same setup as before, but what we see here is UV induced visible fluorescence, using that Nichia 365nm UV LED lamp as exciter. No filter was used in that case, so what we see here is a mix of visual and UV light. Actually this creates quite a test case for UV lenses, since it clearly shows, how well both wavebands (UV + VIS) are corrected in terms of focus shift.

UV Rodagon 60mm:

EL Nikkor 3.5/63mm:

X50 calibrated lens for UV 50mm [looks differently since I had another light on...]:

X90 calibrated lens for UV 90mm:

X135 calibrated lens for UV 135mm:

And now, a few days later, that rare UV Rodagon 150mm.
UV Rodagon 150mm:

So I hope you also found these results useful....

Stay tuned, more will follow on that fascinating subject...
