hello,
I think the camera is very sensitive even if a little hard landing.
The film is lost, is there a way to beat it?

then you need to soften the blow. Micro sd card wil lget lost if you keep having hard crashs, we are all unsure how hard you play. maybe some foam wrapped around. some tape over the micro slot

It is hard to tell from one video of landscape for me to tell, if there is no distortion. Can you say that it removes distortion completelly?

There are thick black borders around the useful part of the image, so it makes the useful part sort of small for FPV. The lag is less than that of a GoPro, which is good.

I think the recorded quality is impressive though. I'm using the D lens and it's much sharper than the iPhone magnetic lens that I used to use. The post below contains 2 recent videos (not live out) of mine using the #16 v2 with D lens:

There are NO black borders on the sides from the native video out. If you have them it is because of the way your TV or monitor is set-up to display composite video. There ARE black borders on top and bottom due to the letterboxed display to fit the full AOV of the 16:9 aspect ratio image in the composite video 4:3 aspect ratio frame. The proof is in the attached frame grab of a video shot with the camera with video out being displayed on my TV.

A little flight with my AXN and 808 #16.
AXN Clouds Fly - Wing View (8 min 5 sec)

Forgive my mediocre flight skills, I've only been flying for about a week.

That is awful!
The amount of barrel distortion is appalling!
I've never seen that with my #16 with the D lens.
Most of mine look like this...
I'm presuming the camera is looking out from a box, which gives the edge vignetting.

I assume its prety obvious an add on lens is in front for extra wide angle

is there some raw footage from cam mounted on a bicyle?

If you are replying to me, I added a 185 degree fish eye to the lens and I have not modified the 808 case yet which is why the edge of lens is visible.

I wanted the fish eye look as I will also be using the camera on my bike, it makes shakiness much less noticeable, and of course the FOV of the 185 can't really be compared with.

I put the .67 Kodak lens in front of my HK A-Cam, and got a really bad image.
I see no point in trying to "improve" the D lens field of view, it's at the limit of acceptable distortion.

To each his own - I don't mind the distortion. And the lens I am using is much wider than the one you show there.

I'd love to have an ultra-wide with minimal distortion like with my DSLR and Tokina 11-16mm, but with the tiny sensor on this camera I know that this is not possible so I opted to live with the distortion and get a great FOV.

It's not something I feel worth pursuing.
At ground level, without the horizon flying up and down like a butterfly's wings, the extreme wide angle you have may not be objectionable.

Here is a photo taken with my phone.


Not great by any means, a ton of chromatic aberration on the edges, the center is decent.. I find it to be acceptable for my uses.

I believe people add fisheye lenses in front of a A or B lens
which is kind of easy

in front of a D lens it would be almost impossible due to the shape of it and they would get the distorsion you got
maybe tbob18 has a A or B lens
maybe he can photograph the final adapt of the lens and show us
its a quite good result and only the farrrrrr corners are cut and quite evenly

Sparky you got a D lens so you dont need much more wide angle
but people with A & B lenses do

I have the A lens, if it was any wider and there would not be much picture. I could have gotten the D lens, but I wanted something a bit wider.

I did take my 808 apart and found that even with the fish eye right up to the built in lens there is still some vignetting, although the edges are a bit sharper. The 180 degree lens may have been a better fit.
