Detection range is 1cm to 12 metres.

It is already with the board fabricator and we'll have the production samples back in 10-14 days so it will be added to the campaign and be deliverable with the AFX. Three motors.

It would depend on demand as there would be a fair amount of development work to incorporate its protocol.

It depends on the stiffness of the lens but although the motor has a USB power input so can be powered from 5v it can actually take up to 14.8v which improves its torque to help this situation. Tilta make a P-Tap to USB cable to enable you to do this and the extra power increases the torque from 0.65N-m to 1.00N-m.

There is a switchable preference for out of range detection in AF-C which is to hold at current position or move to your calibrated infinity point.

To be fair, the clamp weighs 125g so its not bringing too much to the party weight wise. The interior diameter of the ring of the controller is 22.5mm so fabricating infill donut for that with an interior hole for a 15mm or 19mm rod is doable for someone if that is their preference.

You would treat it as two different lenses (i.e. lens without CU is Lens One and regular lens + CU lens is Lens Two) so you would make two calibrations. There is a limit to the number of calibration points you can make per lens but in reality it is so hight that you will get bored of the process before you hit it. The detection range of the sensor is 12 metres. Yes, this is an additional new interface that will be available for order on the Indiegogo campaign page in the next 10 days and will be ship at the same time as the AFX. In all likelihood, it will actually support three motors. I just hope that Belle and Bingo, not to mention Aty, can forgive me the favouritism.

For BMPCC4K/6K everything is automatic. For manual lenses, you are prompted to load the last one that you used.

Yes and then it stores them in its database for recall as and when you need them. For the BM cameras, this recall is automatic as we can read the camera name from the lens as soon as you attach it but for other cameras it will have to be selected from a list. When you calibrate the lens for other cameras you select each element from a list so : CAMERA BRAND >>CANON,NIKON,SONY etc. MODEL >> 1,2,3,4 etc LENS BRAND >> Canon, Nikon, Sigma etc LENS MM >> 18,20,24,28 etc LENS F >> 1.4,1.8,2.0 etc SUB >> 1,2,3,4 The reason that the MODEL field is numeric is that an exhaustive list of every model from every manufacturer is to cumbersome to manage, the storage space is better used elsewhere and we would be needing to issue firmware updates every time a new model is released. So if you have an A7Riii, an A7Sii and an A6500 then you are going to have to decide for yourself which one you designate as 1,2,3,4 etc. Realistically, if you have two Sony full frame cameras and mount the AFX in the hotshoe then you will likely not need to calibrate for each camera but it takes less than five minutes and is only done once so its not much of a hardship. With regard to SUB that is there for if you have multiple lenses that share the same brand, focal length and f stop as a way to differentiate them and again in the interests of overhead the onus is on the user to decide that. In terms of capacity, there is one but its set at a level that can accommodate all of the cameras and lenses owned by @Andrew Reid so the rest of us will be barely scratching the surface 😉

We've experimented with some beacon stuff but the accuracy isn't there for critical focus applications without a lot of setup and tuning in a very controlled environment so isn't practical at the moment. Thank you for the support. We slipped the announcement back to finalise some component and design choices and make the delivery schedule more accurate. It will be hardware and connects via BLE to the AFX and the AFX will ship with the support for it already in the firmware. Price is subject to finalisation but it will certainly be less than €200 with an additional support reward discount for AFX backers.

Almost forgot, if you press the bottom trigger, while holding the stick to the right and double tap the C button you get a power up combo

No, as with the the electronic lenses on the P4K/6K, everything is done on the AFX itself with the controller. You tape a focus target on a wall (nothing fancy, anything contrasty will do so you can just put a piece of newspaper up if you want), focus the lens at minimum focus with the controller operating the focus movement, mark the point using the A button on the controller and this stores the focus point with its associated distance. Move back, re-focus, re-mark etc until you reach infinity and thats it done. Takes no more than 5-6 minutes per lens and only has to be done once as the calibration is stored on the AFX in its database and re-loaded when you put that lens on. In the case of the P4K/6K it is done automatically as it can read the lens name but for motor versions you just select it from a list. If you want to re-calibrate for any reason, you can pick the particular lens from the database in the setup menu, delete it and re-do it. As above, no app required as everything is mapped to buttons/joystick positions on the controller.

Thanks for your support. Have to play that one close to my chest for now. But it won't be far behind the AFX so the suspense won't last too long !

Yes, they will connect wirelessly. The AFX acts as the hub device controlling the camera (and lens motors for manual focus lenses) and receives/sends data to/from the additional components. An example of this that is built in already is the Tilta control wheel when using BMPCC4K/6K. It connects over BLE to the AFX and the AFX then translates its movements into controlling the native electronic lenses on the camera. This means that P4K/6K cameras can have the advantage of the more tactile control of a focus wheel without having to have focus motors and powering them etc. So in the same way, the additional module to offer AI based focus detection will process the data onboard and then pass that wirelessly to the AFX to action on the camera/lens motors.

It will auto focus to closest point in the central area. You control the switch between AF and manual modes with a trigger on the controller. So you can be manually focused and then press the trigger and it will engage the AF. In AF-S mode it will then not re-adjust until you press the trigger again so you can just use it to get and initial lock and then manually adjust from there or you can switch to AF-C mode where it will constantly re-focus on whatever is in the central area. The QuadLock system lets you set four different focus points in the scene either manually or using AF-S and then switch between them with adjustable transition time. QuadLock also has an additional function where you set one of the previously stored points as a target and then manually focus and it will automatically stop when you reach the target focus position ensuring that you do not overshoot. It will work with those cameras with manual focus lenses but it will obviously not do any of the camera parameter control and motorless operations that the BM cameras can use. The core AFX module does not support eye or body AF. But the next add on module for it does.

Yes it does. So if you have the Nano wheel you can also use it to set focus points for the QuadLock system etc. You can use one of these clamps like this and then that gives you the 1/4 20 thread so the ability to mount it on an arm etc etc A two pack of them with ball head adapters are £17 on Amazon and will give you a lot of flexibility and are just generally useful bits of kit. https://www.amazon.co.uk/2Pack-ChromLives-Camera-Clamp-Monitor/dp/B07GZ1D4BB

Its an option but would require an additional USB module for the AFX too. I'm not ruling that out (as it would suit other cameras too) but there a couple of other modules ahead of it in the development queue.

The issue with the FP is that the only way to control it is through the USB port which then, of course, stops you shooting to SSD So whilst we were keen to support the FP (as we love the camera) its likely going to be too much of a trade off for users to be a viable option. Thanks for your support.

Its a fixed internal rechargeable. It can be powered and simultaneously charged through USB.

Indeed it is. Pity I didn't know, you could have come down and had a demo !

Three days to go. The RAW shooting Sigma fp with the Baveyes 645 medium format speed booster is a little powerhouse. Particularly when you can now add ToF autofocus to that manual Mamiya 35mm lens.

If you want to tick every wide angle box for both cameras then Canon's full frame 11-24mm f4 L would certainly be the front runner. Unfortunately, even the used price of them means you'd also be ticking the box that said "please make me considerably poorer".
