NX Mini with legacy manual lenses?

In another post on this forum I can see NX mini with the adapter and lenses mounted on it.

Looks extraordinary and sure not very convenient:

While I keep thinking this again, I suppose it would be best to see an NX-mini to C-mount adapter.

With a C-mount lens, the NX mini would still remain mini while expanding its capabilities.

I want to try this in the future, when I will have a C-mount lens on my hands, so if there is any relevant information, it would be good to know.

I have noticed this ad yesterday. Did anybody try this?

I have another idea, how about directly using the NX-M body cap and remove the center part for the mount and combine this with a grind down C or D mount adapter from Pentax Q. Both parts should be grind/sand down to the required flange distance and combine with screws or glue together.

For shorting the pins, how about just typing a thin piece of copper wire on to the 2 pins directly on the camera?

Maybe... but you would not want to use a jury-rigged thing like that for much. For example, tape coming off could result in the wire hitting your sensor. A 3D-printed adapter like I'm talking about could be usable with ordinary care, pretty much like any other adapter.... It is also likely to be much more precise in the lens positioning.

Do you really have access to a 3d printer with tolerances to do a precise optical mount with no light leak, yet can't afford $200 for a mini? And have a bunch of q-mount lenses you're trying to adapt?

Is this a theoretical discussion or do you really plan to print a mount, and afterwards buy a camera?

I checked with the seller. He told the 2 contacts are connected in the rear with a plastic item that blocks the main item. I requested him for FD adapter. He sent the details of working in the facebook link (pasted here).

Wow, thanks for the heads up. I was waiting for this D mount for a while and I thought no one would ever produce them.

But I find it strange that there is no electrical contact on the adapter, I thought it is needed to for the shutter to fire.

There is an electrical contact on the adapter. This seller has made also a C mount adapter for NX mini, as I had requested here some months ago. If you look carefully at the pictures of the C mount adapter on ebay, you will understand that there is electrical contact and i will help you for this:

Some months ago i had requested here (if you read this thread), that someone could make a C mount adapter for NX mini. No one answered and also it seemed that people here were interested only for an adapter for dslr legacy lenses and not an adapter for TV lenses. And so I started making the adapter by myself: I had discovered some secrets which I had posted here before.

When i started making the adapter I discovered more about the schematics and the electric contacts which you will see in the picture below:

Samsung NX mini electric contact schematics to "shoot without a lens"

( I noticed today that dpreview images do not show [at least in my country] due to an http error. If you cannot see the image above, you can find it at: http://4.bp.blogspot.com/-4JXEx6317Y4/VVTKZAeY6gI/AAAAAAAAF7k/2xQl_fYNCzA/s1600/IMG_1536aw.jpg   )

In order for NX mini to "shoot without a lens" pin 11 (which is for the lens presence) must be short circuited with ground (-). The ground is a. Pin 2 or b. Pin 9 or c. the lens mount.

I guess this is what this ebay seller has made by using a metal adapter: makes a short circuit between pin 11 and and the lens mount and so the NX mini "shoots without a lens".

My DIY Samsung NX mini to C mount Adapter cost to me about 6 US dollars.

If there is interest I will also post here pictures of my DYI adapter, which is only for me of course .

I just have one question. With such a tiny camera isn't it ridiculous to hang big glass on it. What is the point of a tiny camera and giant lenses?? Absolutely crazy...

If you use the official Samsung NX to NX-mini adapter then you will use big and heavy lenses.

But if you have a Samsung NX-mini to C or D mount adapter, then you can use some small in size primes which are usually very fast. That is why i wanted the C mount adapter, which I finally built by myself.

Here is a picture of my DIY Samsung NX mini to C mount adapter with a 25mm f:1,4 TV lens attached:

And here is a test shot taken with my DIY adapter and the Chinese 25mm f:1,4 TV lens. An extra c mount 5mm ring has been used to allow macro:

Dear ihkim,

Thanks for great sharing for the 3d Model preview of mount.

I purchased one 2nd hand Nx mini and  I modified it to an IR camera already, as I don't find a cmount adapter with pins on the market, I decide to build one by 3D printer.

Would you mind to share the 3D model of the mount with me?

Look forward to your reply.

Thank you very much.

Samson

What would it take to reverse engineer the NX lens mount?

That is such a brilliant work!!!

I am inspired from your work, I reverse engineered NX mini lens mount.

Based on your info,  i printed a 3D model.

Thanks

Samson

Samson, is it possible to get the STL Printing file?

hey there

do any of you guys know the pitch, minimum and maximum diameters for a c mount female thread.

I am working on an adapter but it is more universal so I will take out the screws on the camera and replace the metal plate (from which one measures flange distance) and change the flange distance to 10.0mm with my new plate (which has the pin connections so it will be a permanent solution for that too.

the one end of this plate will be a fine thread so now all i have to do is create other parts with this thread to mount and voila. for example the second part I will mount on my plate will be Cmount-> [this thread] im making. And I will make multiple adapters for this such as canon fd, exakta, m42, m39 ....

I need the female thread specs of c mount for now to actually finish the first one.

When Im done with it i will upload the parts sp everyone can 3d print. (obviously I will try first if it works or not)

I would apreciate any detailed pitch and diameter information for c mount. I use metric system and c mount is not metric so I am confused.

Hey guys

so I actually finished the designing of the parts and I was not really sure how to produce it. It is a two part system so you take out the metal ring on your camera and put the first part and fix it (it also has the required holes to make the wire connection to override the lens problem).

basically the first part changes the flange distance to 10mm and then the second part simply connects to the first one with any lense. I made one for c mount and one for m39 but I need to print it and try it out first.

For this project I learned how to 3d print and bought myself a 3d printer. I am going to finish building the 3d printer first and start printing. Instead of printing every time I thought maybe I would post process the first 3d printed part and make a mold for those to make it out of epoxy.

Now I have a question for you guys. Does anyone know how to program properly? If we can improve the fps and bitrate of the video output and maybe even change the compression to improve sensor output we can turn this little thing into a video monster. Even with what I am doing rn I will be able to mount c mount tv lenses on it and will film with it.

I am thinking of making a mold and putting finished set on ebay with a cheap price but I am in Europe and I dont know how useful that would be for the most of you.

I will continue updates when I print out the first one. I also bought another samsung nx mini after getting too excited.

Peace

Very interesting project. This eBay seller used to sell NX mini adapters for c and leica mounts.

It's a shame Samsung stopped making cameras. A NX Mini mkii could have been great: 4k, better continuous autofocus, a few more buttons or a dial, etc...
