mirekti Posted October 30, 2020 Share Posted October 30, 2020 For manual lenses, does this work when the close up lens is added? For example my lens goes from 1.1 - infinity, but when I add a close up lens it is from 0.5m - 1m. Should I simply calibrate at different spots between 0.5m and 1m? How many calibration spots are there? Also, what is the range in which the sensor works? BTM_Pix 1 Quote Link to comment Share on other sites More sharing options...
leslie Posted October 31, 2020 Share Posted October 31, 2020 thinking way... outside the box but can you control two motors ? Like if i had a taking lens and anamorphic lens would it be possible to calibrate both lenses then not have to worry about a single focus solution ? pryde, BTM_Pix and m0fe 3 Quote Link to comment Share on other sites More sharing options...

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. 39 minutes ago, leslie said: thinking way... outside the box but can you control two motors ?

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. 36 minutes ago, MrSMW said: Shout out to Kotaro and Hanna for making the interview 😬 I just hope that Belle and Bingo, not to mention Aty, can forgive me the favouritism. majoraxis 1 Quote Link to comment Share on other sites More sharing options...

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.

One more, please. Let's say I had AFC on, and focus at 3m, the target goes out of frame, and the next target is some 25m away. Will the focus point remain at 3m, move to infinity or move to something in between? Quote Link to comment Share on other sites More sharing options...

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. mirekti and pryde 2 Quote Link to comment Share on other sites More sharing options...

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.

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.

Specifically, I'm wondering whether the unit will be usable with macro lenses at close focusing distances. Detection range is 1cm to 12 metres.

Does the unit tilt down easily to compensate for the parallax problems (the unit will be aimed above the subject and the subject will not be in the center of the LIDAR's field of view) that would arise using macro lenses at distances less than 5 or 6 cm?

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 😉 Many thanks for the comprehensive answer. My order is now placed! Quote Link to comment Share on other sites More sharing options...
Bkn Soc of Cinematography Posted November 4, 2020 Share Posted November 4, 2020 Can you control the focus point to the left or right side of frame or is it center frame only? Quote Link to comment Share on other sites More sharing options...
Caleb Genheimer Posted November 5, 2020 Share Posted November 5, 2020 I have a module request for down the road consideration: a wireless distance readout/display. Countless ACs/DOPs use the Tilta gear on mid-grade shoots, but despise their generic “0-100” readout at the controller. While it would require some pre-production profile calibration work, many would pick up the AFX for this feature alone: real foot/meter readings at the hand wheel. I know this can be read at the AFX, but often focus is wireless for the simple reason that it is being pulled from a distance.
