The problem there is that while 100x150mm filters are ok to carry, 150x170mm filters are HUGE and a bit of a pain.

At least the Irix can have a 95mm polariser attached, or a 95mm ND filter.
Yes you are right I guess they would be a bit of a hassle to deal with.The more I look at that Irix lens the better it looks...

Obviously you wouldn't have grads, only screw-in solid ND and Polariser, but with the K-1 you are going to have a lot of dynamic range to work with, so grads are somewhat less important.

True but I still use grads on my 645z even though it has BAGS of DR. Its a hard habit to get out of But yes at least you could attach an ND or polarizer and maybe you could even get away with hand holding a 100x150 grad in front of the lens?

I still use grads too on really tough scenes, you can't avoid it.

Bombo holder name Laser100SE is the only one 100mm filter's holder can use 95mm ring thread and it can use for Irix 15mm f/2.4 also lots of Medium/ Large format lens

I believe Formatt Hitech also does a 95mm adapter to allow their 100mm holder (and potentially others) to be used:

Threaded Adapter for 100mm Aluminum Holder ? Formatt-Hitech

Zomei also makes one (I use the Zomei filter holder and filters - very good for a budget line):

https://www.amazon.co.uk/Zomei%C2%AE-Square-Filter-Support-Adapter/dp/B00IZCF6EU

I'm not sure whether these would be suitable on a UWA lens, but worth checking...

We have a good news for Pentax users who plan to visit our stand at Photokina fairs. We received today our first lenses with Pentax mount that are ready for try during the show:-)

Sure wish they would get this lens on the market. Still not sure if B&H or Adorama will be carrying it.

Too late for me I just bought a 15-30 I was interested in the Irix but in the end I decided having a zoom would be preferable for versatility as I do shoot architecture occasionally and 15mm is way to wide for interiors. I still haven't solved the filters issue but I might end up with a Nisi system or just manage without them.
