Dear According to your experiences. Is it recommended to use wide-angle cameras? Are they useful if I keep my focal length constant? To perform terrestrial photogrammetry ... according to your experiences what is the maximum distance to work with respect to the object of interest?

Hi Jose,
you can safely use wide angle cameras. It's helpful to have the same focal lenght in clusters, but you're free to change it. Meaning, if you change the focal lenght, make sure to take more than 1 or 2 pictures but take a whole cluster of it.
The distance is different and depends on the subject you're shooting and the required accuracy. This GSD calculator may help https://www.3dflow.net/ground-sampli...ce-calculator/ -
