Filter Holder for Samyang / Rokinon 14/2.8?

I've just ordered a Samyang (Rokinon) 14mm /2,8 (Manual Focus).

Mostly for Astrophotography.

But since the Wide angle is really nice for scenic shots of waterfalls with long exposures I am also looking for some kind of ND-Filter for it.

Samyang has their own.
But where will I find good quality filters for this holder? And what kind of ND-filters are there?
Are they a special size or something I could use (with the right holder) for other lenses as well?


Any other options of filter holders that might be better?

Haida makes one. https://www.amazon.com …amyang-14mm/dp/B012BH5U0E

It takes any of the 150mm filters including the Haida filters.

The 150mm filters is more standard than the 161 x 139 that is with the Samyang holder?

I have only shopped for these filters and have no personal experience with any of them. What I have found is most of the highly recommended and also the common brands of filters have 150mm square filters.

The main problem with them is is the 150mm filters, for a top of the line ones, get really expensive. In my opinion, get a 150mm if you are really serious about getting the best from this setup, or get the Corkern/Samyang if you just want something to work.

150mm filers are also available for light pollution filters for astro work so that is something to consider too. I do not know if a quality one of those is made for the Samyang holder or not.

Of course, as I stated earlier I have no experience with any of these filters. Hopefully someone who has used one of these setups will join this conversation and contribute some first hand experience.
