I have both cameras and use the X4S for mapping and the X5S for videography. Now i'm fully aware that the global shutter of the X4S makes it the ideal camera for mapping however the X5S with 25mm lens is, if i'm not mistaken, twice the focal length of the X4S. This of course means that my GSD would be better wit hthe X5S at the same AGL.
I know Pix4D can correct for the distortions introduced by the rolling shutter so if i needed to stay high but still aquire an good GSD, would the X5S still do a good job. What would i be looking for if I was to do a comparison?
