A zoom lens simply means a lens where you can change the field of view, which would be used in combination with a lens encoder to calibrate multiple steps across the zoom range. 

There doesn’t have to be a specific setting for fisheye lenses, since any non-zoom lens is fixed. 

Question is, why are you using a fisheye lens? Those lenses have a lot of distortion and really aren’t suitable for virtual production. Maybe the distortion is too much for the calibrator to detect a sharp image of the calibration board? Are you sure you’ve printed the calibration board correctly, by the way?

Finally, the Camera Calibrator is both for calibrating the lens and for the tracker to camera offset. The offset is calibrated in a separate step, after you’ve completed the lens calibration. What tracking system are you using?

Hi I am using HTC Vivetracker

hi I hope so

Is that the image out of the camera? If not, a screen shot of what the camera sees would help. 

Also, the squares on the checkerboards pattern are clearly miss aligned, if you look at the first row on the left. I think it needs to be more accurate than that. The size of the boar must also be 100% accurate.

Hi,

It is very unlikely you will be able to accurately align the papers by hand.

You should either ask a local printing service with these specifications: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/tracking/camera-calibrator/#recommendations
Or order the board from Aximmetry: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/tracking/camera-calibrator/#buying-the-boards-from-aximmetry

Warmest regards,
