I'm working on focus stacking / focus racking support. I've solved everything unknown but few details and since you were interested in it:
How many shots do you typically want? I'll make it customizable but I need something initial (I generally use waaay too much so I need some saner defaults)?
Would you want a full rack option? Going from mfd to infinity in some number of steps?
Would video while racking? Almost like focus after shot?
Would you want exposure bracketing during this?
@ihkim
I can dump a bunch of data for lens from command line (you can too) with st command. Do you need it?

I'm no way expert in this kind of photography, due to the necessity of having the proper equipment, if NO automated function is present on camera. I triedseveral times, with little success.
Reading around, I see that optimal number of shots vary, going from ~5 to dozens. Personally, I would not want dozens of pics to stitch together. My ideal number would be 10-15.
For the range, ideally I'd like to be able to set a min-max and then given the number of shots, the focus moves by a discrete delta to cover the interval. Min max could be set in this way: move focus manually, press ok (min is set) then focus manually, press ok (max set).
I didn't understand your other question about video. I don't need live view or anything else. Just the output shots :-D
Imo, exposure should be fixed during shots.

make it simple and move on, update later , just keep it up Otto !
Hi,Could someone please explain how you "extract busybox from the NX300 package and copy it to the SD card as telnetd"
Would love to tinker around and look at this but unfortunately my Linux knowledge isn't much.
I have downloaded the NX300 file and I can find a busybox directory but cant see a binary.
Thanks, any help would be appreciated.

... how about focus pulling for video?
nx500 has pretty decent focusing, so focus racking I guess may be useful for some image compositing later (simulate soft-focus, etc), but I can't say I'd use it.
but if you shoot video, pulling focus can be very useful.
let say you have a dialogue between two people, and you want to switch the focus between them while they speak, at the moment there isn't a graceful way to do it.
But let's say you preset a focal distances, and you switch between them with half-press shutter, so you focus, you start recording, and when you need to quickly and accurately re-focus, you half-press the shutter button, and when you want to go back to the previous focus, you depress it.
So in essence, using some combination of keys, to set current focal distance be recorded as the preset-value before you have started recording the video.
Then you refocus for the start of the scene and you start recording, and when half-pressing the shutter button, current focal distance is saved as temp-value, and camera is refocusing to preset-value distance.
When the shutter button is released, camera is refocusing to temp-value.
(re-saving the focus-value each time the shutter button is half-pressed will allow for some manual focus pulling, and jumping to - and back, to the pre-specified focal distance)
... and if that happens I'll be miserable as all (but the kit) lens I have are manual only

Agree.
Clever, but it would be better to do such things with the touch screen. The new a6300 supposedly has an amazing 4D focusing system, but no touch screen..go figure..... how about focus pulling for video?

NX500 has very good focusing and I couldn't care less about the Sony.
But try it, and you'll see touchscreen is not that useful for video focus pulling.
especially when shooting hand-held pressing the screen will shake your camera, and you can't really hold the camera comfortable while doing it.
It will be much more ergonomic and useful to be able to do it with by half-pressing the shutter button to get a preset focal distance (no focus hunting, and introducing least possible vibrations while comfortably holding the camera)

I haven't done handheld video for the last 8 years, and then, I did because it was a scene on a short horror film that I had to do it-and actually I used a Manfrotto Fig Rig (the wheel, right), and the only case I used AF the last 20 years, is recently with the Canon C100markII, which really makes you realize why Canon, even though they are so conservative with their machines, are still number one, because things just work!
Just last week, on a corporate video, we used the Ronin for a scene, and even that wasn't Panther dolly worthy;
and when you are hand held, how are you really sure about the focus you have measure? even a few cm off, and you have lost it.
My wish is, camera on a tripod, a "documentary street" style scene, and myself just tapping around,
John Smith style, but with a NX!

Actually the NX1 allows changing focus point in video by touching screen!

you can "nail the focus" ahead of time, with the x8 MF preview.
Once you have that set, of course it will depend on the scene, and how much DoF you have, if you do it handheld.
Even on a tripod, changing the focus point via the touchscreen won't produce as good results as preset focus pull.
If you are hand-held and moving, I've seen one way to "keep steady distance" by have a rope on the waist of the actor and cameramen, which gives them some idea how much distance they need to keep (assuming of course the actor is filmed above the waist).
again, this is something that can be used on the cheap without much gear, nor expensive setup, and doable on a gorilla-shoots.

so does the NX500 ;-)
I have both. I would rather see them had a similar Canon Dual Pixel AF feel through the touchscreen, but it is too late for than now, or not? They just put it in their new Galaxy phone!

can't you already do that with the Samsung app?
(I think you were able to change camera settings and take pics, but not sure if you could change the focus)

NX500's focusing is quite good, and can't see a reason why you would want to change it.
Especially considering I'm a former Canon DSLR user, who had to shoot 3-4 pics (refocusing each) just to make sure the lens did not back-focus, and comparing it now with the fast and always on focus NX500 pics.
I agree that the AF is very good but not for pro work.
Have you used the C100markII? This is the only AF system for pro work I have ever used. Probably that's why the same technology is in the new Galaxy camera phone!
I am experimenting (really slowly) with NX1 now, but I am not happy with anything so far.

Don't you pull focus manually anyway, if you are doing "pro work"?
The dual pixel focusing is a hardware "thing", so you won't be able to do it with software, and will increase AF performance in low light, other than that, NX500's doin' fine imho = ]

otto k was kind enough (we owe him big thanks) not only for figuring things out, but for making it simple = ]
follow those instructions:
https://github.com/ottokiksmaler/nx500/blob/master/Customizing keys.md
you can simply turn telnet on by pressing "EV+Mobile"
