Enrico had already announced about existence of this filter in his post here: http://www.ultraviol...celab-u-filter/

And here is the link to the sellers web page: http://www.primaluce...-uv-filter.html

I also recently recieved this filter and tested it for pictorial UV-photography, despite scarce sun and strong northern winds.

Here are few first pictures, all shot with full-spectum NEX-6 and Leitz Focotar-2 50mm lens.

As you can see falce colours produced with it are different from what we used to get with Baader-U2, but I really like how this filter works with some subjects. I think it will be great for artistic UV-photography and I am going to experiment with it more in the nearest future and update this thread with new pictures.

Alex, do you have any information of the exposure time of your shots compared to say the Baader U?

Hi Bjørn, I did not compare both filters directly. I was mostly interested in its pictorial qualities.
EXIF data is present in the pictures i posted.
The first shot was done with F/8, ISO 200, exposure 2 sec.
Other shots were done with F/5.6, ISO 1600, exposure ranging between 1/20th to 1/40 second.

WB was different for different shots, plus additional edits in Photoshop

Thanks Alex
It will be interesting to see a UV sparticle test with this full range on a camera capable of recording this range.
I hope this guy gets a 50.8mm version out, I'll have to save & wait, & get some shorter then 340nm narrow band filters to add to my sparticle.

There is already a 2" (50.8 mm) version available on the PrimaLuceLab web site, which I purchased. The diameter of the glass itself (after removing it from the filter mount) is 45.9 mm, so it cannot be remounted in a 52 mm filter ring like I did with other 2" filters.

The thread is different from our M48,M49 or M52 mm "normal" filters (I think, it is also mentioned on the Primaluce site).

I found a M52mm holder of a macro adapter lens, where it fit in perfectly (filter plus frame) and I just glued it there with some drops of glue:

This is an old threat, but I got some more pictures with the PrimLuce recently, now with the D810uvir and again with the UV-Nikkor. Processed with Photo Ninja and PSCC. All taken hand held.
It seems this filter cuts a bit more of the blue around 400nm compared to the Baader U and maybe it leaks a tiny bit of IR.
