Hi,

In the past I have used the INON UCL-165 and UCL-330 wet lenses with my compact camera. Since I have now switched to a NIKON D7000, these lenses are collecting dust. I wonder whether it's worth to buy the Dyron M77 adapter (and M67 step ring) for my Hugyfot housing?

I would use it combination with the Nikon AF-D 60mm. I have a Kenko 1.4 teleconverter too, but the wetlens would allow me to switch underwater, which may be an advantage.

I use the UCL 330 & 165 as wet diopters with my Canon 100mm. Conveniently the Nauticam macro port is 67mm threaded but I believe there are a few adapters available for ports which are not directly compatible. I don't use the UCLs with my Canon 60mm as the working distance becomes far too short.

Using wet diopters is far more flexible than a TC, though on occasions I do enjoy fitting either a 12mm or 25mm extension tube which will probably become my preferred choice with FX macro.

Hi Jef,
I used an UCL 165 on one trip with my 105 mm macro and in the end i decided to sell it again because i found the optical quality wasn't not good enough. All images were too soft IMO. But you can get the 67mm adapter anyway as there are plenty of other wet diopters like the Subsees (the +5 or +10). I use those now and i'm totally satisfied with them, even with the D800.
Like Timmoranuk mentioned: it's not really useful to apply wet diopters to a 60 mm macrolens, as the closest focus distance will end up probably inside the lens. On the website of reefnet you can calculate the expected maximum magnification ratio with different lenses when the +5 or +10 Subsee diopter is applied.

succes, Udo

I already tried the subsee calculator. The UCL-165 is a +6 diopter (1/0.165), and would give a 1.2 magnification ratio with the 60mm. However, I did not take into account the change in minimum focus distance. In that case the 1.4x converter will be more useful in combination with the 60mm I assume.

The main reason why I considered buying the Dyron adapter is that I already have the Inon lenses, and thus it would be relative cheap to try.
