Experiences with IRIX filter holder IFH-100 and IRIX 100/100x150-Filters?

Hi everybody,

if you own an UWA lens with filter thread of 95mm and want to use 100mm filters there's the new IRIX option. Somewhat more restricted than a Haida or Lee system, but the Haida / Lee system only supports up to 82mm filter threads.

What are your experiences - if any - with the IRIX system on the IRIX 15 and/or other lenses by example with smaller filter thread using an adaptor ring.

Any opinions about the IRIX ND / GND filters compared to Haida and Lee filters?

Is it possible to combine the IRIX system with the IRIX 95mm CPL filter?

Thank's for all replies!

Regards, acoufap

For the neutral density past, I suggest you get hold of the bower set that includes .3, .6..9 density - made for the back of the lens, and/or add the eight or nine stop Kodak Wratten, or other, ND to the mix. Pretty simple to cut the Wratten into numerous filters for the back, but make sure to round-off edges. Then you can add a polarizer to the front without stacking, if you really need one. I got my Kodak ND;s at B&H and my Bower pre-cut set off of Ebay, incidentally.
