Metabones currently offer a type 2 adapter which will fit the OM-1 this is the m43 to Canon EF lens adapter. The Nauticam N85-N120 adapter for Nauticam ports was designed to use any Canon EF lens with any m43 camera, but they chose to design the adapter for the speedbooster, which was not needed for the 8-15 and adapting other EF lenses to m43 was probably not required as the m43 manufacturers have a very complete range of lenses. There's no shortage of second hand 8-15s though and they are not that hard to find for sale.

I think it's more likely that Nauticam decided that WWL/WACP etc were the future for them so trimmed the range of offered ports and adapters. It's a pity as the 8-15 on m43 is an excellent option.

I suppose that makes more sense, I know the 8-15 is still available used but Nauticam seems to be trimming their products a fair bit and I would guess things that work only with discontinued lenses would be high on the list of of things to cut. But that is just guesswork.

Back when I was shooting M43 I was strongly considering getting the bits together to use the Canon 8-15, but then I moved to APS-C and a Nikon 8-15.
