Lins-Barroso Posted September 4, 2019 Share #1 Posted September 4, 2019 (edited) Advertisement (gone after registration) We know they are MADE IN JAPAN, but what is the manufacturer of them: HOYA or MARUMI?

Advertisement Posted September 4, 2019 Posted September 4, 2019 Hi Lins-Barroso, Take a look here What is the Leica's supplier of the new UVa II Filters: HOYA or MARUMI?. I'm sure you'll find what you were looking for!
jaapv Posted September 4, 2019 Share #2 Posted September 4, 2019 Most likely not Hoya. At the time that Leica supplied the IR filters they stressed that their supplier was Japanese but not Hoya. 1 Link to post Share on other sites More sharing options...

The Leica UV/IR boxes say "Made in Germany" so i always thought their glass were made by Schneider but i may be wrong. 1 Link to post Share on other sites More sharing options...

They are series I but it seems that series II are made in Japan. It would be interesting to know who makes them. 1 Link to post Share on other sites More sharing options...

It would be interesting to know who makes them. UVa II filters are indeed made in Japan as it is printed on their box at least but i don't know by whom. I was just replying to Jaap about UV/IR filters which were made in Germany i believe but Jaap seems to have different infos about that. Sorry for the OT. 1 Link to post Share on other sites More sharing options...
jaapv Posted September 4, 2019 Share #7 Posted September 4, 2019 Advertisement (gone after registration) No, they weren't made in Germany. That was confirmed by Leica in an interview (don't ask - that was 2006-2007 !) and also privately to me by a (quite p***ed-off) official representative of B+W/Schott. it may well be that the final assembly eneobled a "made in Germany "label. 1 Link to post Share on other sites More sharing options...

jaapv Posted September 4, 2019 Share #9 Posted September 4, 2019 Yeah - your camera is "made in Germany" - from 90% non-German parts... The problem at the time was that the only UV/IR blocking optical glass in the world was available in Japan. This glass is made in limited runs and Schott was unable to produce at short notice. 1 Link to post Share on other sites More sharing options...

The glass is too important in a filter to claim that it is made in Germany if it is not the truth i believe but i'm not specialized in this field of law. 1 Link to post Share on other sites More sharing options...
earleygallery Posted September 4, 2019 Share #11 Posted September 4, 2019 Glass and filter rings shipped to Leica in Germany, put together and packaged there = 'Made in Germany'. I'm curious why it matters who makes the glass? Presumably it's of decent enough quality to do the intended job? Who makes the card for the boxes? Who does the printing? Which logistics company do they use to ship them? So many unanswered questions! 1 Link to post Share on other sites More sharing options...
Matlock Posted September 4, 2019 Share #12 Posted September 4, 2019 The laws in most countries stipulate that, providing the final assembly is carried out in that country, the product can carry the statement "made in …..". If it were not so then Leica cameras would carry a very different statement as would many, many products. 1 Link to post Share on other sites More sharing options...

Given the price we pay for Leica ones, a decent enough quality is not what i did expect when i bought mines for my M8.2 but it's just me... perhaps . 1 Link to post Share on other sites More sharing options...
jaapv Posted September 4, 2019 Share #14 Posted September 4, 2019 I think it may be Marumi - their top line filters are quite good., Leica rarely if ever made their own filters, they were generally rebranded. 1 Link to post Share on other sites More sharing options...

But surely you'd trust Leica to use a good quality supplier? It might horrify some to know that Hoya supply some of the glass for lens elements to Leica. 2 2 Link to post Share on other sites More sharing options...

wizard Posted September 4, 2019 Share #18 Posted September 4, 2019 AFAIK, Hoya made the aspherical lens element used in the MATE, and Hoya stopping to make that element caused the death of the MATE. While Leica initially tried to source this lens element from another (Japanese) supplier after Hoya had stopped supply, the resuls were lackluster, and only relatively few copies of the MATE with the alternative source lens element were made. Leica then decided to stop producing the MATE. So all in all, I would say Hoya ranks among the top suppliers for optical glass. 1 Link to post Share on other sites More sharing options...
