The best thing is that you will have one ND filter for all lenses that you will use with speedbooster no matter lens diameter. 
It would be great but question is additional price and if there is enough space to add another glass element.
Honestly - 500 bucks quite lot for me but I completely understand that price.

Any chance to add at least variable ND like this in it to make it even more usable and versitile?

After much work and many sleepless nights, I have almost finished my work and I think I have brought the lens NXL to the point of being sold to the public.
I thought if the test this week will be positive to produce it with Canon EF mount dumb to which you can add a Nikon adapter with iris aperture control.
At this stage it allows to mount all Nikon and Canon lenses, in the future I will continue to work to enable the electronic control of the lenses.

This is the focal test:
1 picture, NX1 + NXL adapter + 50mm Nikkor Nikon 1.4 AF (aperture F8, Focal 50mm);
2 picture, NX1 + 16-50 OIS (aperture F8, Focal 38mm);
3 picture, NX1 + 16-50 OIS ( aperture F8, Focal 50mm).
(All picture it's taken freehand).
 
Are welcome your comments!

I can't imagine using my Nikon mount Samyangs 1.5T Cine lenses with your speedbooster! Finaly great 35mm lens with ultra nice low light performance AND Fullframe like DOF!. The Same for my 85mm. And now I could actually have LESS lenses, because one lens work for two focal distances.

Liam Have faith, and again a few weeks of patience.
Before selling my NXL adapter, I have to do many tests to be sure that it works best.
As soon as I finish the "pre-series" model in the early days of August, I'll start with pre-orders. 

Hi Cojocaru, I'm currently testing another positioning of the lens near to the sensor. that allows me to gain a few millimeters to distance to the camera lens.
The first tests are very encouraging and I hope to have the lens pre-series ready for August.
 

That adapter looks really well made! I'm impressed. So are you planning to do smart stuff? Maybe I can help you with that

Hallo NX World, the NX Booster it's coming soon! This is the Prototype Mark II. 
Marco do not worry, if I do not post my progress, is because I have a lot of work in my private life. Next week I start the test with Nx1 camera.

Another quick test (this is one of the first test) the lens still is not perfectly aligned, and this creates a little blur in the lower part.
Nevertheless, it also corrects distortion, behaving in the opposite way to the way a wide angle.
Also, you can see the brightness gain of 1 stop in dark areas.

Hi Pavel, Sure! I got it from focal reducer lens system on the market, but I could not install it on an existing adapter, if it was that simple, they would have done! I had to build a tool for finding the correct position of the lens (focal distance flnge), I also had to make changes to the lens and body NX100 camera. My first experiment was only to see if it would work. The second step was to understand if no changes to the body it would work. This is another success, the spaces are tight but it works perfectly. I started the third step now, the SB Adapter construction for Samsung NX1! (Work on Nikon lenses because I can manually adjust the aperture, but I tested it also with M42 lenses, and with bayonet mount).

Sorry, I do not have electronic knowledge to build smart adapter. But I think that, in the future something like Aputure Dec or similar is possible.
Hi Kidzrevil, first of all, I thank you because you have put together a Samsung camera enthusiasts. I soon, when I'm done with my testing, I will begin a Kickstarter for the construction of the Speed Boster NX. At this time it is premature.

I always thought that Speedbooster for NX mount should be possible becuase Samyang 12mm NX exists. In theory - it is one lens specialized only to mirrorless system which is be adapted to Sony FE, Fuji, Panasonic, etc. and also to NX mount.  
Difference between mounts is in flange distance. NX flange distance is probably the longest between all mirrorless systems and that was reason why Metabones thought that it is not possible to create speedbooster for NX mount. However Samyang 12mm NX (according my opinion) is proof that it is possible to built optical system wich will work across multiple mirrorless mounts. Why it should not be possible for Speedbooster?
Speedbooster for NX mount would be great... I am keen for more information. I think we can forgot on inteligent adapter but Speedbooster (even manual) would be great!! 

Yes Marco, it's a speed booster prototype selfmade. It's possible. In the nex time I post my full work on it, and begginning the test on NX1 camera.

Someone know if with hacks it possible to set manual focus in video mode, without setting it every times?

Here is the Focus Pull test video with EV based script in NX-KS 1.59m, 100 mbps for steady result

I can confirm Outerbeats findings. I was lurking in the shadows until something bigger happens, but my video assignment for today made me to step forward and try to install the hack.
To my findings it was super easy and the hack works perfectly with my budget card Transcend Ultimate 600x 64GB SDXC 90MB/s Class 10 (which offeres best price/performance for the lowest price). The card heats up, but as others said already, until its hot to melting point (which won't happen), no problem at all. With that NX1 can do
- 200mbit for 6 sec
- 195mbit for aprox. 6,5 minut
- 190mbit no stopping after 12 minutes.. 

Not sure what changed, but great job guys, very much so!
