Photogrammetry Prime Lenses vs "default" zoom lenses...? EXAMPLES of scans?
Hello I was wondering, i have heard that prime lenses (=fixed focal lenght= you cannot "zoom" - for example just 50mm) have superior visual quality in comparison to "zoom lenses" (lenses that have variable focal length, for example from 18mm to 55mm) and probably even more superior visual quality of the final photos in… -

I never did an exact comparison but my guess you would be perfectly fine with your default zoom lens once you are not actually using zoom within a single photo series. Any time I tried to use varying focal distance photos it always ended in artifacts or interruptions in point cloud generated . Reality capture would be… -

Just keep in mind that what you see in test pictures done of tripod in studio lighting is not what would you get of hands in a… -
