Psychedelic Lilly - a UV and VIS comparison Noflexar 35mm vs EL-Nikkor 80mm

A really nice flower, a "Stargazer Lilly", so let's see how the beauty of that flower will look like through the well known Novoflex Noflexar 3.5/35mm versus the newly rediscovered older (chrome/black) 5.6/80mm EL-Nikkor enlarger lens in visible light, but also in invisible UV.

All shots were done at f8, ISO400, 1/160s using Xenon flash, exposure adjusted using flash power control and ND filters. UV shots were done using the Baader-U filter.

Here now a VIS-UV differential using the Noflexar 3.5/35mm:


and yes, quite a nice sharp lens with quite good UV transmission and some little focus shift.

and here using the 5.6/80mm EL-Nikkor:


Quite a sharp lens, even less focus shift and also quite good UV transmission.

For comparison here the VIS shot using the Noflexar 3.5/35mm:


and using the 5.6/80mm EL-Nikkor:


Finally now the UV shot using the Noflexar 3.5/35mm:


and using the 5.6/80mm EL-Nikkor:


Well, I am surprised to see, that the Noflexar gets slightly outperformed by the EL-Nikkor 80mm!

BUT: I tried the 5.6/80mm EL-Nikkor outside for infinity tests and unfortunately it seems to have a very prominent large UV hotspot which renders it unuseable for that...


P.S.: the 80mm EL-Nikkor (the older, chrome black full metal type) has an adapter ring on its base with outer M39x26tpi screw mount (Leica enlarger mount). Beneath it is a M25 thread for older #00 shutters. Company Schneider Optics offers adapter rings, if that one should be missing (oder code 92-013251).
P.P.S.: the filter thread of that older EL-Nikkor 80mm is 34.5mm, which is pretty uncommon, as me if you need an adapter ring.

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