It's never going to happen.

Sony won't allow it.  They will never allow it.

Kinefinity can say "future adaptors" all they like.  Sony run a closed eco-system.  This is their MO.

Sony own the mount.  No other camera other than one made by Sony will have a native E mount.

Lens adapters to Sony e-mount already exist. A Kinefinity mount can just be an adapter.

Reverse engineering is entirely legal too.

I'm still trying to find a supplier for the e-ND that can make a larger piece so slightly back burnered at the moment while I concentrate on other things.

The electronic part does work in concert with my other controllers such as this one (and the app as well actually) so when it happens it will be integrated.

Currently, the size of the glass that I have is only really suitable for in mount versions, which is a bit of an issue with cameras such as the P4K which relies on speed boosters.

Anyway, I've just done a quick and dirty pic (literally when you see the finger prints all over the glass) to illustrate what the build along would have been with the smaller piece. 

I used the MicroBit as the controller (in an electric blue DIY case obviously) as its cheap and easy to program for everyone (although I would obviously provide the source code) so at its very, very basic component level this is how it works and you could finesse it from there in terms of housing etc. and not using croc cables to connect it!

In this version you just use the two buttons to increment and decrement the ND level as seen here at 0%, 50% and 90% reduction although you can scale it anyway you want.

Another advantage of the MicroBit is that it has a very simple Bluetooth link function so you can use a second one to remote control it.

When I source the bigger piece, I'll put it up properly but thought it might be interesting to you in terms of how it works as it will be exactly the same simple principle but bigger!

I'm actually pondering a mechanical version of it at this point though....

The Holy Material EXISTS!!

Good luck with the project mate!

My dear erstwhile member can you please stop attacking John Brawley now. I have long since given up on camera forum arguments so might not be completely up on who is right and who is wrong-evil /

I like the pictures. A lot.  This camera will probably replace the micro cinema camera for me as it’s not much bigger and is much easier to work with.  I didn’t feel as strongly about the 4K

What a shame. Who are these "deep state" BMD insiders that are here pushing an agenda ? Myself and Hook.  Who else ?  What do you guys think, there's a plot and conspiracy ?  You guys don't wat t

Wait till you see what this one does.....

I love big knobs! Tell us! (Nice "marketing" picture also).

As of the ND solution, in mount is good enough for me, as I will be using it run n gun with native m43 glass and then is when I need most an e-ND solution.

I could do both options of course.

Seriously, if I set the ND issue I am ordering the P4K the next day.

Its for focus control.

Unlike the small Record Start/Stop one, this one can control all the parameters as well as monitor them.

It also has the multiple recallable Aperture/ISO/Shutter/Temp/Tint memory slots functionality from my app.

The focus controller works with native MFT lenses and EF lenses on Metabones smart adapters and has adjustable rotation range (i.e. how many complete turns it takes to go from minimum focus to infinity) and one shot AF by pressing the wheel in.

As per my app it has storable focus points with the option to instantly switch or with a selectable transition rate.

The big difference with this though is that there is also a manual option where you control the transition with the wheel.

Internal battery recharged by USB and can also be used while being charged that way too.

Time from switch on to connected and controlling the camera is around 3 seconds so a lot quicker than an app.

Haha....it was just a quick picture to show @Andrew Reid that it is daylight viewable.

It is actually a terrible marketing picture for my balcony wall cleaning skills though  !

@BTM_Pix thought so, but its even better ofcourse!

Is this going to be kickstarted also?

After the Lukilink fiasco I "promised" myself I would never kickstart again, but I can easily change my mind anyway!

Congrats, you are on a roll as of late!

All those increase the usability of the P4K significantly.

I am not lying when I say that I will get the camera because of you. 

Thank you.

Yes it will be on Kickstarter.

I understand the apprehension about Kickstarter to be honest but rest assured nothing of mine will ever be going on there until it is ready to go from a functionality point of view, which both this and the small one already more or less are.

The problems with Kickstarter invariably happen when it is being used to fund development rather than just funding production.

I'll put up a small video when time allows next week to show both of them in operation.

The small one has another trick (or two) up its sleeve that I'll also show in the video.

Can you develop an app to bring the same functionality to an Apple Watch or smartwatch? 

You mean you don't like the very stylish red strapped version of this one ?

;)

The AppleWatch is something I've considered (as well as the Android equivalents when I made the app) but, in all honesty, my conclusion was that its overkill for this task in terms of complexity and certainly in terms of cost.

The advantage with this (apart from it only being €60) is that you can attach it to a tripod or gimbal far easier than a watch and the expansion port offers us more possibility to extend what it can control.

It'll make more sense when you see one of the expansion units.

Hi,

really nice!

I would add a blocking mecanism, to block all buttons. 

Keep on

You mean you would like to lock out controls from being able to be operated from the camera itself ?

The over exposed highlights are ugly. 

I think that blown out highlights might be the worst aspect of poor quality digital, for me at least.  Worse even than poor resolution, over-sharpening, or low-bitrates with macro-blocking.

That's one of the primary benefits of shooting with 10+ bit depth, you can expose for the greatest DR and then choose your middle exposure in post while applying a nice highlight roll-off, and do it without breaking the image.  To this end, I haven't really noticed the DR of my GH5 being too low as I can normally get the exposure I want and also not clip highlights.
