All this would be reasonable if I was a begginer.
But Im 5 years work with photohraphomety. (most time in PhotoScan)
That why I fill myself stupid. ))))
I never have problems like this before, than I works with my old Canon`s cameras. (In RC and in Photoscan)
I never had some extra paranoia about stability, focus or image quantity.
And I have same problems with 40 and with 120 photos.
