For me the 5.4mm lens was perfect field of view of 64 degrees...but that lens design is long in the tooth so presently for good resolution for 4K etc. I guess the 8.2 is all we have, I agree 42 degrees may be too tight for some things...but once I've got it in my hands I'll find out for sure...it will be great for flying low and close without having to fly too low or too close. I think mappers will like it because there will be no distortion but more photos will have to be taken. It's basically a 35mm lens in 35mm camera parlance. It will also magnify vibration so smooth flying will be critical much more critical.
