What I can do is an AF Adapter like Techart Pro but with opening control function and stabilizer for Canon EF lenses.

Autofocus S Samsung lenses in M mode (for instance the one with the center pane), is not much different as speed and accuracy than 30mm lens.

With Canon lens aperture control would be directly from the camera (without external control).

You can not have conversion data from Samsung camera in Canon lenses. This would involve major compatibility problems, errors and continuous crash.

This system is 100% safe, with 100% lenses compatibility, including M42 and old manual lenses.

Only fault, you can not merge with NXL due to the bulkiness of the motherboard.

you have other questions?

Thank you for answering my question.

I like this a lot more than the original suggested things. I personally think people expect too much even Metabones do not work as well as people claim it does, (personal experience) non speedbooster support would not be an issue as there are a ton of Canon EF APS-C lenses out there anyway.

As I understand the Samsung cameras are extremely sought after right now including their hardware that is why prices keep rising, because they are becoming rarer and rarer and its mostly because of this forum right now and the great guys behind the bitrate hack and Luca's adapter and work in progress smart adapter.

Not to mention Samsung NX1 and NX500 imao are still amazing cameras and they are cheap well used to be anyway. Its a good sign because now that dirty "&()!"%)¤ acting president of Samsung aka Son of Samsung's actual president, is in jail and that means there will be a brighter future for Samsung now that the corrupt bastards are removed.

So I was not quite sure about what went on so I read it 3 times now, so as far as I understand Luca you are using the Samsung 30mm lens to make some form of super Techart Pro adapter for Canon EF mount but also works with old lenses or is it just a EF to NX mount but with similar properties to a Techart Pro?

The 16-50mm F/2-2.8 lens is great but my biggest issue is its heavy weight, huge size for its calibre compared to a Sony 16-50mm F/2.8 which I fell in love with but only works with A-mounts.

I also think people have misconception of autofocus in Samsung lenses, only the S lenses work the best, all the other are okayish to good, a lot of the older Samsung zoom lenses are pretty slow and inaccurate most of the time because they are old and were intended for older autofocus methods Samsung used.
Expecting Canon to work as good as S lenses on Samsung NX1 and NX500 is theoretically impossible.

But the 30mm Luca showed has good speed, it would be interesting to see it in action with video.

However Luca, I think you should clarify better what type of smart adapter you are trying to make, fuck the price right now, what exactly will it do and what will it be for?
Because I think there is some misconception out there that must be cleared out.

I read somewhere that the NX mount is based on K-mount since Samsung used to partner with Pentax and a lot of their earlier cameras were cheaper Pentax knock offs down to the sensor.

Samsung apparently had a prototype of the K-mount that supposedly had Autofocus etc here is a picture of it.

Is it not easier to adapt the Pentax K-mount to the NX with autofocus?? I know majority wants Canon but lets face it, autofocus might not be the greatest on it if any at all.
and at the end of the day Pentax is still in the business making cameras and lenses, Samsung is not.

When I started to think about building a smart autofocus adapter, I asked you if you preferred the Techart Pro adapter or Aputure Dec AF.
Almost all of you have responded Techart Pro, and in fact, to have an autofocus system that works with all lenses that's cool!
So I started to think what could be a fast way to have it in the real world and not in the world of dreams ..
The 30mm f2 pancake is long 21.5mm (half a millimeter longer of adapter Nikon/NX), it has no buttons OIS, Zoom or another, it's just a fixed lens which has two functions:

1) Autofocus
2) Iris.

These characteristics make it the perfect candidate to become an AF adapter.

First I ceck the range of focus, it is 6mm (Techart Pro it's only 4,5mm).

 

After I disassembled the rear flange, I raised the board and looked inside, the electric motor is positioned laterally and all the gears rotate the rear part of the ferrule, the main gear is located in the rear part of the lens, and this is good, why not cluttered and provides more space for mounting the front lens.

Inside there is the motor for the opening of the iris and is parallel to the support cylinder for glasses.
In general, having taken the measurements, I can state that it is possible to convert the lens in a 30mm AF adapter.

if there is enough space, you can install the pin Canon EF mount on the front of the commands to activate Stabilizer and Aperture Iris with micro Arduino.

Up to here I made simple but to obtain an AF adapter is necessary to construct a new outer ring of aluminum with two or three linear bearings to support the weight of the new lenses, build a new internal support in aluminum with front flange of the lens assembly and perhaps replace some plastic with new gears in aluminum gear.
The width of engagement Nikon is ok, but the width of the Canon is greater, then I have to redesign the whole body.

Such a change could cost about 400 euro, this could be a bargain for those with a 30mm, but considering the prices soared Samsung lenses may exceed 650 euro for a complete adapter.

Having a third-party adapter with AF lenses is possible.
This is only one of the possibilities, I have other ideas and solutions to build AF adapter.
I wrote this post to know from you what you think.

 

Is there no one who can help you do custom PCB design?? 
There are plenty of websites were you can order cheap custom PCB you designed yourself. 

I can only do very basic PCB designs, but there must be someone here who can do more complicated stuff, or even fund someone to do it for you that would be a possibility.

Helo John, But you do not preferred a similar adapter to Techart Pro?

Not if it does not support modern lenses and I wont be able to get stabiliser, no point in having only autofocus and no stabilisation going on, but it if it does everything damn, hell yeah.

I rather have true camera to lens connection than having to remote control this, its pretty safe to say that a good majority of us actually uses the autofocus in video quite a lot, because its superb and hits the target more often than not. 

If this was translated to a Canon mount, imao it be gold worth, its too much work going around with a steady cam and a remote controller just to get focus all the time, good for big video production but not so much for us who just have the camera with nothing else, run and gun style.

Anyone who wants to edit H265 I highly recommend get a graphics card that has native hardware acceleration for VP9 and H265 like the new AMD Radeon Rx 4xx series cards or the nVidia GeForce GTX 10xx series cards. 

AMD APU from 7xxx and 8xxx including 9xxx series support H265 and VP9 out the box and therefore excellent for editing this footage. I really recommend compatible hardware, this way you wont have to transcode them all the time. 
Managed to secure myself a GeForce GTX 1070 8GB MXM card for my laptop from Gigabyte in China.

Hello everyone, these days I started working in a new project for the construction of an smart adapter, by accident I discovered that the NX1 offers 2.4GHz and 5GHz Wi-Fi wireless networking connectivity compatible with IEEE 802.11b/g/n, as well as the faster 802.11ac standard which has enough bandwidth to stream 4K video wirelessly over 500Mbit/s.
Can anyone verify this?

Is it not easier to get the camera to just dump 500mbit/s video files to an external harddrive via the USB 3.0 port?

Samsung NX1 Vs Canon 1D X Mark II  http://cameradecision.com/compare/Samsung-NX1-vs-Canon-EOS-1D-X-Mark-II

Sometimes I do not get Samsung, they make the most perfect mirrorless APS-C camera that still trolls competition even today, and yet makes exploding phones and expensive lack cluster high end stuff including stupid Wifi fridges. 

Seems like their strength lies in Cameras and not wifi fridges

I have reflected on the possibility of building a smart adapter,
But before working on this project I would like to ask you friends of the forum, which would you prefer:

1) Aputure Dec
2) Techart Pro

Aputure Dec has the advantage of remote manual control, no mechanism on the adapter, built-in battery, open the iris and the display showing the iris aperture values.

Disadvantages, it works only with Canon EF lenses.

Techart Pro has the extraordinary advantage of transforming all manual lenses with auto focus lenses, and since the thickness can mount almost all existing lenses.

Disadvantages, can not adjust the aperture of the iris of Canon EF lenses, no remote control.

This question is not an official communication to work on Autofocus system to Samsung, this depends on the time and money that I can spend, I just want to do a survey to see what you prefer.

I look forward to hearing your opinions.

- write 1) for Apture Dec; 

- write 2) for Techart Pro.

Thank you

Is it impossible at this stage to make an electronic adapter? 

Techart Pro with electric connection to lens for stabiliser would be amazing, its no point if the electronic lens is not activated and it just adjusted it as if was a manual lens, there was a guy who managed to make the Samsung communicate with Canon lenses with a conversion board.

This one is the V2??

i have heard about something here that if you get a 4k 4:2:0 you can convert to 1080p 4:2:2 what about that?

Yes 1080p to 444 more like through downscaling.
You can downscale and get more information just fine, but adding more shadow information is impossible at the moment, the program has to be so intelligent it literally has to know what is there but never really is present in the video footage to begin with.

There is actually a near program I have for downscaling footage, its called ClipToolz Convert V2 and its free the V3 and V4 are paid ones.

I Spent many nights to create the NXL, I started with a vision and with the contribution of all those who have bought and tried I could improve it.
The boards of all were useful, I alone could not test it with all the lenses and detect the defects, a project carried out in crowdfunding is this.
To answer your question, I must tell you that in reality this would be the Mark XXX version, but I prefer to stick to the NXL version.
Currently, the construction costs are very high because it has made in Italy and in a limited number of pieces, so I can not reduce the price, but it remains a good investment given the rarity of the piece, maybe will be revaluated as anamorphic lenses.

 ALSO I AM SURE THAT SAMSUNG RESUME PRODUCTION OF CAMERAS JUST HAVE INTERNAL PROBLEMS SOLVED AND REORGANIZED THEIR COMPANY.

Can you mark the new release with a v2 at least? So I know I buy the latest version and not the old one.

Yes I too hope Samsung stops being fools and restart production of their new camera.

Hello. Someone says he wrote a program to rebuild color sampling 4.2.0 in a real 4.4.4.
I'm not a programmer or hackers, or anyone good as @ottok or @kinoseed can see better what is it?

Thank you

Looks similar to those AVISynth scripts were you can convert 420 or 411 to 444 full RGB but yeah its not "real" 444 has details cannot be reintroduced in fact you loose information in the process no matter what.

Only through downscaling can you obtain details.

But Gh5 shoot in burst mode h265 6k 10bit 4.2.2 with Metabones speed booster it's as aps-c sensor, but no cheap solution.....

You honestly might just get the KineMAX 6k for a similar price tag and enjoy 6k RAW video or 2k 200+fps

thank you .... does the hack allow it to run the focus peaking on a manuall lense activated after a camera restart?

Not sure but a simple button push will let you use focus peaking anyway, Kinoseed one remembers your focus position after restart with wirefocus lenses if you set it in the options.

Kinoseed one is the slowest to load but its packed with features, the Vasile one is more video oriented and its as fast as a vanilla NX1/NX500

I didn't either! these are Max Yuryev's numbers! But I did some gigs these summer/autumn with GH4 or a6300, and the a6300 ISO was matching the NX's much better than the GH4, so I was expecting quite a difference, but this is more that I could have imagined! 

Pana is definitely going the right way, but it seems that the sensor is really at its limits. The Panasonic executive said that in order to increase the total megapixels and so had to put smaller ones, which increased noise and blah blah blah. The conclusion is that after 3 years, and 4 megapixels more, they can't go 1 full stop further. Sony showed with their new crop sensors that they can go 6400 easily, and this is their main selling point as of now; something that Fuji took it, and made it a real camera!

All that I want to see, is a video camera with the GH5 insides around 4.000$/euros/money.

True I never liked the MFT sensor size, I always been APS-C guy, full frames were usually heavy and bulky until the Sony A7 series came out but those are plagued by horrible ergonomic designs and a menu that reminds me of early Windows 3.1 days. 

It seems to be most manufacturers keep compromising one things all the time, GH5 looks very nice in video department, but its probably going to get outdone in photography by even the NX500

I would expect the 3200ISO to be somewhere around 1600 true NX ISO. They probably have better file manipulation (better in camera settings and handle of noise and codec).

Also, I saw a dynamic range review that in reality the latest 20mgpxl Pana sensors are 1 stop less than GH4, so newer m4/3 are not that better than before. I am expecting the GH5 to be the best among all, even the Panasonic Uematsu said that DR is the same though. 

6400ISO

Samsung NX1 5281 ISO

Sony a6000 5185 ISO

Canon 7DmarkII 5105 ISO

Nikon D500 4705 ISO

Olympus E-M1 3870 ISO

Panasonic GH4 3835 ISO

Aright I never did compare them side by side so, I tested the NX500 and NX1 at new year, my NX500 uses the kitlens LOL just because I did not want to fiddle around with the F2 lens I have which is all manual and it looks pretty good despite being at 2000 ISO on the NX500 but the NX1 was max 1600

I was just looking at GH5 ... this thing looks really sweet.
Most of it functionality (minus the 5D-IS, etc) could have been available even in NX500... there is no technical reason why it couldn't have been available, and the production cost would have remained the same. I really really really hope those Samsung execs have been fired ! (although I doubt it)

Adding "crop option" for NX1 would be just the same as removing it from nx500. It will have to be done through modifying the scanning PPU setting.
And we can't "up our game" :))) we are not the producers of the cameras, and simply modding 2 yr old technology can't make wonders.

I think Panasonic just gave a great lesson on product placement, development and PR. The directors in Samsung should pay attention, and find execs who actually can deliver like Pana does.

Although Pana should have not made this separate :
- Paid upgrade to enable V-LogL video capture with LUT-based preview display
(as it will hurt the image a lot, and not make much additional profit, and be incentive for a product hack):

 

Anyway, I'm still using my trusty ol' nx500, but even though the GH5 sensor is small and there is no BLI, I'll probably move to camp GH5 next.

One thing the Panasonics have going for them since the G7 is workable ISO up to 3200, and no I am not pulling this one out of my back. Have a look for yourself:

Seems like with autofocus on the camera uses a lot of processing power just for that alone so 140mbps is the most stable but sometimes, just sometimes on the NX500 it will tell you your card is too slow when you enable autofocus with 140mbps bitrate. 

With AF disabled it seems it can do 200 with Lexar's 2000x card, I only have Lexar cards to test so I would not know what the SanDisk can do.

Hi. 

What is the "main" download Website for those hacks?

Is there also a improvement in the usability of the menue?

https://www.facebook.com/NXKS2/

It seems the camera industry is moving away from enthusiast photographers to professionals for full steam now, the reason why I think the NX series did so badly is because they were targeting regular people like smartphone users instead of the professionals. 

I come to a point in my life were having the latest and best is vanity, I had my Xperia Z for almost 4 years now and I see that I rarely use it for much else than what you would not be able to do in a low end device anyway, sure it may not have the fastest processor out there and not the greatest camera even for its own class back then, but it gets the job done.

The same goes for my camera, its materialistic obsessive to continue purchasing newer and newer products because you want the quality to be superior, its not true a good camera wont make you a good photographer, its the way you use that camera that makes you a good photographer, whether your work turns out good or not. 
I seen modern Chinese movies shot with 16mm Soviet cameras you can get off eBay for like 80 dollars and these movies have better cinematography than most Hollywood movies and they were a lot more enjoyable story wise too. 

GH5 looks like a good camera no doubt and price wise is very good as well 1999 dollars for such great features? Its a steal if you ask me. 

But I too used to be like "Quality matters" but I had time to use my NX1 now which in a few months now is almost 3 years old, think about that for a second, over 2 years old and still produces excellent images and video, the hack has also done a lot for us but it would been even better if they managed to make it spit out MJPEG's with little to no in-camera processing specially making it shoot 2160p60, but I wont complain they did an excellent job non the less. 

I for one wont be upgrading for a long while, this camera will stay with me for at least 6 years in total, and one day I will use it for a full feature film, I grew up with Soviet cinema and I know that masterpieces are not dependant on camera equipment but only the ingenuity if their production crews. 

This does not mean a shitty Nokia phone camera is the tool for the job, there is of course a limit and there always will be, for photography most pro photographers seem to say that around 4 to 6 megapixels is really the sweet spot for digital delivery but if you go print you must go higher, 1080p seems to be that sweet spot too, even though 35mm produces up to 6k digital prints if it is low clean ISO film, 1080p still looks great even on a big screen but for me 2k is minimum in a cinema, most cinema projectors are only 2k too. 

Its been a while since 4k has been out and overall the adoption of 4k screens is very slow still, 1080p came out for the first time in the late 80s, you can start to imagine now how long it will be before 4k is universal standard for everything. They did not even start to get serious about 1080p until 2006 when Blu Ray was being released despite there being a delivery format that supported HD delivery in the 90s like the D-VHS and MuseLD.

Another thing I noticed, majority of movies and TV-series are produced at low cost and quality is not generally very important, often they just rent big 4k cameras without giving much about its capabilities as long as it just shoots the resolution they are happy enough. 
Also most Hollywood films these days are shot behind green screens and more time is spent in the editing rooms than the scene. 
A good camera is not essential these days even in the industry as most movies uses low range colours and shadows and purposely crushed, video for TV are usually decapitated before being broadcasted in order to limit the bitrate they often kill colour depth and destroy dynamic range to fit it in the standard hence they end up looking very greyish. 

The workflow with RAW video is painful, I rather not go through with that again LOL, NX1 gets the job done for its pricetag and I see a lot of people with even cheaper cameras making amazing videos on YouTube specially those Japanese videographers and photographers. 

Yours is pretty good, these days I care less about quality and more about getting pretty shots.
