The previous two answers aren't much help and neither gives the correct answerCan someone tell me the approximate area the camera can “see” (looking straight down) from 400’ up?
The field of view would depend on the focal length of the lens and the dimensions of the sensor in the drone. If you could provide that information it would be easier for someone to help you. I have a P4P V2 for which I calculated the field of view using the FOV Calculator mentioned in this thread. It confirms Meta4's information for the P4P. I am including a capture of the calculator with the data entered for the P4P and have used 100 feet as the primary distance and 400 feet as the secondary calculation. Hope this helps. Note that I mislabeled the sensor size as lens dimensions. It is the sensor dimensions as indicated on the chart.Can someone tell me the approximate area the camera can “see” (looking straight down) from 400’ up?
Thanks
I don't believe anyone is "shooting anyone down". As you mentioned, it's about helping others. Where the disappointment comes in is when some people respond wanting to help but they really don't know. People ask questions in a forum to get help and learn. How can that happen when you have those who answer without even bothering to research the topic so they have the knowledge to help. For instance, I posted a question about P4P batteries from a 3rd party vendor. I only got one reply and it was a rant that didn't make any sense at all and had nothing to do with my question. It was a complete waste of time for me to read it, It must also have been a waste of time for the responder to sit down and write it. I just wish I had that much time on my hands to waste everyone's time with my senseless rants. Correcting wrong information is not shooting down for the sake of shooting down. It is simply someone who knows what he is talking about correcting the wrong information being disseminated. That in itself should be considered a learning experience. I do a lot of reading here but little responding to questions because I know there are a lot more people on here who know a lot more than I do. So I just read and learn, rather that trying to impress others with inaccurate information.Ok I think nobody should awnser any question around here cause mr meta seems to know everything so let him speak,,send all your questions to him cause we all not matter by his reply,,well they were trying g to help but still wrong,,the president has spoken,,this why I dont coment on much anymore,,,its learning but when your shot down all the time why the hell bother,,I wonded where everyone went
Ok understand,,was pissed when I read your reply but see your right,,I'm just crazy,,I was ready to chuck it all in,on some pretty heavy meds and definitely not thinking normal,cant fly drugged so I'm pissed off but not ranting,you will know,much respect to all here from asking to the reply part,,@Meta4 is a clever bugger so it's just bit odd he leaves a lot hanging while we play guessing games,,ay it's not a first and I bite my tongue on that,must thank y @Phantomwolf and you meta ,more input ay less popcornI don't believe anyone is "shooting anyone down".

It is my opinion that forums such as this lose more members due to the senseless rants and offers of misinformation than they do by those knowledgeable members making sure the information posted is accurate. I am very grateful there are people who are willing to take the time and share their knowledge with others freely. Thank you all. Just my feelings and remember, if you correct a genius, he will thank you. If you correct an imbecile, he will criticize you. Think about it. In which category to you place yourself? Just remember, people get to be knowledgeable by spending valuable time learning about something. They don't waste their time with senseless rants or shooting people down for the hell of it. They have much more important things to do with their valuable time.
Sorry to do this but...So revisiting those calculations for a 1" sensor and 8.8mm FL the vertical axis is approx. 380' and the horizontal is approx. 510'.
And the P3 pro lens focal length is 3.61 mm.I am not able to find the actual focal length for the 2/3" P3A camera but if it is 8.8mm as well then the area seen from 400' would be approx. 260' on the vertical axis and 350' for the horizontal axis.
A search for 'dji drone sensor sizes' came up with this site. I cannot say whether it is accurate because I really don't know. I would say it is a good starting place. DJI Drone Sensor Size Comparison Page — DJZ Photography - Real Estate Photographer, Grand Rapids, MII would like to add a correction to my original comment about the dimensions of the area seen by the Phantom 3A and 4 Pro cameras at 400'. My calculations were based on a focal length of 20mm, however this is incorrect as this figure is the '35mm equivalent' as I now understand it. The actual focal length of the 4P is 8.8mm as indicated in the only reference I could find in a DJI site. So revisiting those calculations for a 1" sensor and 8.8mm FL the vertical axis is approx. 380' and the horizontal is approx. 510'. I am not able to find the actual focal length for the 2/3" P3A camera but if it is 8.8mm as well then the area seen from 400' would be approx. 260' on the vertical axis and 350' for the horizontal axis.
EXCELLENT answer. Even an old fart like me can understand????The previous two answers aren't much help and neither gives the correct answer
If you were asking about the original Phantom 4
The area covered at 400 ft =
640 x 480 ft = 7 acres
If you are asking about the Phantom 4 pro
600 x 400 ft = 5.5 acres
I'm not sure what needs explanation there.What I DONT understand is DJI states on it's website specs:
Phantom 4 pro still photo is 3648 x 5472 pixels. FOV of 84 degrees and a 24mm equiv to 35mm film
Mavic 2 pro still photo is 3648 by 5472 pixels. FOV of 77 degrees and a 28mm equiv. Somebody smarter than me PLEASE explain how this is possible.
Not quite ... it's 514 x 343 ft = 4.05 acresOh, btw, do you happen to already know the ground area the Mavic2Pro would cover from 400' AGL? Would it be around 365x550?
The standard way that all camera makers express the field of view of a lens is the diagonal angle.Some time ago I made dis:
Terrain mapping, Phantom 3 vs Mavic
Just wanted to share an image. To cover the same amount of terrain, Mavic needs to fly 1/3 higher than Phantom 3 Pro. I'm still trying to decide whether I should move to Mavic - it is so much easier to transport...phantompilots.com
Ph4 is somewhere inbetween.
Though not sure how DJI counts FOV.. is it the distance between opposite corner pixels, or distance between the max left and max right on central line?
