I have 2 Evo ii RTK (V2) units and I'm trying to put together calibration parameters for a stockpile quantity measurement software. When I take photos with each UAS, I get different focal lengths reported in the metadata at 1x zoom: 10. 14mm and 10.57mm. I understand that they are very close, but since the larger rounds up to 11mm, that will give the software issues for standard parameters. I have done a camera reset from Explorer and it didn't make a difference. I'm running all the current software/firmware updates as of the post. Any suggestions or information why the same camera model would have different focal lengths?
