Pilot camera - What lense do you like to fly with?

I wonder what kind of lens everyone flies with.

From Hobbywireless:
1.7mm lens has approximate 170 degree field of view
2.1mm lens has approximate 158 degree field of view
2.5mm lens has approximate 147 degree field of view
2.8mm lens has approximate 130 degree field of view
2.9mm lens has approximate 127 degree field of view (Natural Human eye)
3.6mm lens has approximate 92 degree field of view
4.3mm lens has approximate 88 degree field of view
6.0mm lens has approximate 78 degree field of view
8.0mm lens has approximate 58 degree field of view
12 mm lens has approximate 28 degree field of view


I fly with a 3.6mm on a KX181.

Also have a 2.9mm I would like to try.


What lense do you prefeer to fly with?


I would like to see some videos from flights made with a lens wider than 3.6mm.

I use 2.8 for everything. Btw. are u sure about that data for 1/3 sensor? I though that 2.8 is about 90 degree Its not 130 for sure.

2.8 quadrocopter

Quad over the trees (4 min 31 sec)


2.8 plane

Pierwsze plecki FPV (4 min 51 sec)

i fly:
1,8mm
2,1mm
2,5mm
2,8mm
3,2mm
3,6mm
4,0mm

but you are right, with lenses like 2,8mm or less, altitude is hard to estimate.
thats why this crash happened:
2,1mm lens (edges are blurred)
FPV Celaeno Quadro Copter - Fun flying & Crash (1 min 45 sec)

I have change to 2,5mm on this quadro copter and its much better.

here is my Swift Mini with 2,8mm lens:
FPV MS Mini Swift - Fun with trees (4 min 12 sec)

i have changed already to 1,8mm lens, to see more especially in curves.

On NGHobbies 2.8mm is stated as 115 degrees. 3.6mm as 90 degrees.

Cool videos.

I'm using 3.6 mm now.

But moving towards 4 mm and above. Hoping for better resolution as I fly higher altitude and longer distances.

Cool videos.

I dont think they are right. Try some lens calc

Found smth like that and it looks fine, horizontal 81 fov.
http://www.aventuracctv.com/lens_calculator/

Maybe they gave diagonal info...?


Its really up what kind of flights you like. If you like acro - use 2.8 and wider. If you like to fly high... use 3.6 or narrower.

And always.... wider lens for beginning. If u see more, you wont lose yourself

FOV is different between a 1/4, 1/3 or 1/2.5 imagers. I use either a 4mm or 3.6 on a
kx-191.

I am planning to fly low and have fun with chainlink UHF and cloverleaf on the videofeed.

I guess I go for the acro and 2.8mm. Just tried the lens on now in the yard. Looks good.

It won't be more clear. It'll just be shaky and nauseating.

I use 3.6mm lens with a head tracker, like this.
FPV - Skywalker maiden ground recording, antenna demo (14 min 27 sec)

That's a 1/3" CCD camera (RCV922) and FoV is definitely less than 90 degrees, but works
fine with a HT, and there's minimal barrel distortion while panning and tiling.
I might want a little wider if I wasn't using a HT on a fixed wing aircraft.
Here's a vid using a 3.6mm lens on a different 1/3" CCD camera (VSN500 aka SN777) from my tricopter
which gives an idea of what it's like to navigate around stuff with this FoV
FPV - First day Tricopter (5 min 35 sec)


Note that the same lens on a 1/4" sensor will produce a narrower FoV.

Sorry, for clarification, are you asking about experience with "aftermarket lenses" only from your list, or just in general what FOV (field of view) we prefer to fly using even if it's the stock lens?
