Thanks guys.
Actually I have another question -- What about a 100mm holder? Would that fully support the 15-30 (esp considering the smaller filter sizes) or does that lens require 150mm?
From my 'research', it seems the Irix 15mm can use 100mm filters since it accepts a 95mm circular filter (and 100mm > 95mm at diameter). And those 100mm filters and holders are quite a bit cheaper (and tidier) than the 150mm jobbies.

Actually.. it looks like the Haida Holder (haha) has both a device that attaches to the Pentax 15-30 (Tamron but same fit) AND a 95mm adapter ring. It is pricey. But I think that'll do it unless someone has a cheaper option (always welcome).

Yes I've been through that thread already and am aware of those companies. But what I'm not aware of is if anyone has definitively tested any one of those and confirmed one is swappable from the IRIX 15mm onto the Pentax 15-30mm without any extra adapters, rings, or gazonskis.
I'm also aware, for anyone playing at home :lol:, that the IRIX accepts 95mm round filters. But that is a waste to spend 100-200 bucks on a nice NDF that I'd only use on the irix. I'd rather kill 2 birds with 1 stone if possible and just buy a square 150mm system that works on a number of lenses without extras.

Is there a filter holder that will both properly fit the new 15-30mm and the irix 15mm firefly ?
Thinking about an IRIX 15mm lens while I ponder the D-FA 15-30mm later and buying a filter holder that could accommodate both would be super as I could buy the holder and filters now. But is there one that works properly for both?
