I use Reikan Focal to calibrate my lenses, but Focal does not support it. I need to calibrate the lenses and can't wait for Focal software update. Any suggestions?
I shoot photos of a brick wall at an oblique angle to get the adjustment close and then do the final ±1 step tweaking shooting various objects with graphics and text on them. It does not take long and can be done anywhere.
Use manual mode in FoCal - quite easy to do and we've discussed it in earlier threads. I verified with LensAlign or similar setup (target and angled yardstick) afterwards.
