Probably they won't fit in the Sigma rear filter slot as they are 2mm thick. Even if they fit, it will likely cause induced field curvature. Gel filters are only 0.1- 0.3mm thick.

BTW: Aurora already answer me and I will be getting the new Sigma 14-24/2.8 filter set for review (Around December). It looks like an adapter won't be required and they are thin enough to fit into the lens holder.
They are located in Orange County, CA and their owner is a very nice guy and follows FM.
(Not sure if it will fit into the Sigma rear slot though)
Not sure if the filter above is really the thin filter foil or one of their thicker polyester filters. I also haven't found the Lee gel sheet in 0.9 strength in Europe. Is this available in the US?
The 3306 are definitely thin, I have them at home (but currently not yet the 12-24 lens to do some tests).

That's great. I'm very interested in your test results. I will get their MC-11 filters and hope they will work with the Samyang 10mm XP lens.

Looks good. Have you tried the Lee 0.9 Gel sheet on the Sigma?
I only used the Lee 1.2 Gel (4-stop) and liked the results. There is some color shift but it's fixable in post. If you use LR, I can send you a preset.
Gel filters are not perfect though. There is higher incidence of veiling flare when shooting against the light and a small hit in contrast. (In the case of the Lee, it's very small, almost not perceivable)
IMO, the best ND filters available are the Lee Pro Glass IRNDs. (Almost zero color shift even with their 10-stop and no contrast loss!)

I just got this confirmation from Aurora:
"There is no modification required for the Sigma 14-24 E. Our metal frame filter can be dropped into the rear slot and locked by the original tab."

That's good to know. I will probably wait for your test of the Aurora Filters before I buy the Sigma.

Hi JeyB,
I think it looks very good for a zoom lens and unlike primes, we can't expect perfection. I think turning off IBIS made a difference for 14mm.
24mm looks centered although not perfect but I doubt you will notice any discrepancies when shooting real world images. (even astro)
It's a very hard test for any lens. It's rare when all 4 corners look symmetrical even when testing high quality primes. Consider yourself lucky.
Thank you very much, Fred. Really happy to know your opinion, I have no such a big experience testing lenses as you have. So very grateful for your time.
Yes, IBIS was playing some differences. When off, things got better indeed. It is true, perfect zooms are like "green dogs", one in a million. But all in all, and aside the previsible imperfections, the Sigma 14-24 is impressive at all focal lengths. And when stopped down to f5,6 or f8 it becomes tack sharp corner to corner.

That will be wonderful if they come out with rear ND filters in various ND strengths that are easier to handle then the plain gel sheet ND's. I tried using the 4-Stop Lee Gel ND the other day at a water fall and it was nothing but frustration. The breeze and my oversized fingers made handling it very tedious. It was difficult not getting finger prints on the gel as I tried setting it in place and removing it when finished. Once when dismounting the lens it came out somehow without me switching the knob and blew off onto the ground and became a wet gritty mess. Luckily I had my NiSi Holder and Round ND and CPL Filters with me so I left the other cut gels I brought along with me in my camera bag.
I'll try them again when a suitable frame is made for them. I'm hoping to pair them up with my NiSi circular filters to create more ND strengths and to use them paired with my CPL.

Here's another heavily post-processed multi-exposure image from an astro excursion with the Sigma last week. I'm really enjoying the versatility of this lens. After shooting pretty much exclusively with primes for decades, it's really nice to have the whole range of focal lengths available for astro so I can frame the MW to suit the composition at hand. Probably the only WA/UWA lens that might still tempt me at this stage would be a CV or Loxia 15/2.8 for UWA sunstars, and the latter is unlikely to eventuate given the 52mm constraint. These are good times for landscape and astro photographers.

If you are new to astro, a good first step is to find some software to show you what the night sky will look like at different times/dates for your selected location. I find Stellarium great for that. The first time I used it, I chose a dark location that I knew well and used the software to know when the Milky Way would be where I wanted it. When I went out and actually saw the Milky Way just as I had pictured it, it felt a bit like cheating.
For this image, I set up the camera before it was fully dark so I could take some twilight shots to partially blend (for better shadow detail) with more foreground and sky shots later in the night when the moon set and the Milky Way was lower in the sky. Usually I take quite a lot of shots, including for stacking to reduce noise, and the camera has to stay motionless for hours. Post processing of high res images is always very time consuming for me with these types of shots.

This is simply gorgeous! Well worth the effort!
Thanks for your kind words. Luckily I really enjoy sitting out under the stars, even for hours at a time, although perhaps somewhat less on cold nights (peak Milky Way season is in winter in the southern hemisphere).
