Hello,
I have successfully calibrated my Sigma 18 - 35 Zoom lens with the Camera Calibrator for all the zoom levels (with the 6 steps - but they all have the focus value at 0 despite having the correct tracking input etc.).
For my focus tracking to work, I needed to change/edit the profile with the Basic Calibrator and exchange the calibration data if I'm not mistaken. At first, I thought that doing an additional calibration with the Basic Calibrator wouldn't be necessary. But what happens with the data listed from the calibration with the Camera Calibrator? When I just add new points to the profile and let the old ones remain, I have 6 (or 5 deducting the starting point) jumps back to 0 when turning the focus wheel. Thus, I deleted 5 of them. Is this how I'm supposed to do it? I guess I can delete the 6th as well because apart from the focus distance all the other values align anyways ...
It seems to work this way and I can perform the focus tracking within the LED wall project coming from my FIZZ 2 lens data tracker. Zoom is working as well. I'm just confused because I didn't want to delete the data from the Camera Calibrator ...
Best wishes
Hi Martin,
Currently, the Camera Calibrator does not support focus calibration. You need to perform focus calibration within the Basic Calibrator instead.I'm not sure how you are deleting the calibration points or how you would obtain accurate focus data simply by deleting calibration points, unless your tracking device is already sending properly calibrated focus data.
To add focus calibration in the Basic Calibrator, you should introduce three to five additional calibration points for each zoom calibration point that the Camera Calibrator has generated. Each new calibration point should have a different focus value, distributed across the range of focus your lens can use. Additionally, you should use the existing zoom calibration points created by the Camera Calibrator and set the first focus value in them.
Warmest regards,
