I'm an FAA 107 licensed architectural and real estate photographer, flying a Mavic 2 pro. I keep hearing rumors that the sharpest apertures for the Hassy camera on this drone are between f4.5 and f5.6. This is so different from what I'm used to with typical DSLRs that I wonder if it's true or not. In experimenting, I can't honestly see a ton of difference in either sharpness or depth of field between f5.6 and f11 with this drone. Can someone knowledgeable about this wise me up? Also -- does this lens have a focal length in the usual sense? It looks to me roughly equivalent to a 24mm...does anyone know? Thanks.
