You could always file down (carefully ) the upper thread on a filter to reduce the amount of vignetting. I've done it on a couple UV filters in the past, no big deal.Thanks for the info @HabsFan !!
I intend to buy the Haida slim pro ii mc (nd3.0 or nd1.8) which I used with the sony 16mm and i was very satisfied.
If the original file of the above photo has no vignette, then I am happy because there's no need of a larger diameter filter.
I will wait for your stacked sample!!
Alex - I also used the B&W with this Rokinon 12mm. It will vignette. In fact ever ND filter will have some vignetting on a UWA. The angle at which the light enters is already extreme. That's why most UWAs already exhibit vignetting without a filter. the filter ring will block this light further. How much will differ base on a number of things from the intensity of the ND, the thickness of the ring, the lens design. I say this so your expectations are reasonable not to discourage you. As for your experience with the 16, that is not really a UWA. It has 24mm FF eq. Where as the Rokinon is 18mm. You shot both so you already know that difference is like night and day.
Your Haida should be fine if it was good for you on the 16mm, I believe it vignettes less than my B&W. Just keep in mind this is a UWA.
I have to say for someone that shot that 16 for as long as you did, I shocked at this new found pixel peeping attitude. Go out and shoot man!
12/2 with Lee bigstopper on a way to Sunny day
Thank you Gary!!!! Yes i agree 24mm vs 18mm there is a huge difference.
My main concern is to avoid the kind of vignetting that i saw from this clip
Yes the system is very expensive and Im only about to afford the polarizer after some years and one setback from breaking the bigstopper. Im glad the new one came in a metal Box Ill be using my filters on the 12mm, on my 24x36, 645, 6x7 and 4x5" film systems with ND's , grads and polarizer maybe some colored for B&W.Thank you Gary!!!! Yes i agree 24mm vs 18mm there is a huge difference.
My main concern is to avoid the kind of vignetting that i saw from this clipDo you have Gary any sample with the 10nd stop and only lens correction from lightroom?
Thanks for the sample with Lee @soeren !!!
As @NickCyprus mention i try to avoid the 100mm system because of the cost. (The 100mm system that i was looking from hitech will cost me about 400€ for holder, 6stop nd and 3 stop soft grad).
I recently travelled to Europe for the first time, wanting to pack light I nearly left my nex-6 at home. But in the end I did bring it with one apsc lens along with my main camera. I was surely surprised in the end that this was my most used kit for holiday and was very glad I brought it in the end. here are some pics from Italy.

Didn't watch the whole video because I can't understand what he's saying. I found where he put the ND on, and it looks like he's stacking filters. That's why he's getting the vignetting your're seeing. The Rokinon and a good single 10 stop filter will not do that.
As for samples - I just remembered, I still have my B&W ND. I never had a 67mm ND for the Rokinon. I used a step-up ring and a 72mm filter which was shared with the 18-105mm. The larger filter may mitigate the vignetting.
Oh by the way. 100mm systems still use rings for the filter holder, so the size of the filter itself has no bearing on vignetting; It is the lens and the filter ring combination. This is why Lee has special rings for wide angle lenses to reduce vignetting. I attached a good article on vignetting, it even mentions both Lee and Hightech vignetting in one paragraph.
What is Vignetting?
