GSP images out of focus?

[TwinDad2013]

Had a problem the other day while completing a mapping project using GSP. During the first battery the stored images appeared quite out of focus which is peculiar given there is no focus on the P4P sensor. Next battery in the mission was installed and all imagery was of the usual high quality. Final battery again reverted to the blurred image collection.

I have previously completed mapping missions in excess of 3,000 images using the P4 and GSP with this never occurring. Has anyone experienced this before or have any ideas?

Thanks in advance
Paul

Not P4 but my P3A had some photo 'variability' issues when I first got it. On the advice of another P3 owner I balanced the props and made sure I always use the same prop in the same arm (red dots on one black and one silver marked to make sure).

Others say that DJI props are good to go straight from the box but I've only ever seen one balanced prop out of five sets (I'm on my third phantom)

Always worth balancing props IMO, even if it doesn't solve your problem.
