DJI Osmo action Cam/Sideshot

I have the OA too and it is a sweet camera, the systems that use a action camera, dont people put other lenses on those in order to not just have a small round view in the middle of the screen.

It is after all wide angle and i think people use 8 - 14 mm lenses in order to better "zoom" into the reticle. ?

I am not taking my OA apart for anything like that,,,,, hell no, also a good 4K megapixel lens are not cheap, even when you like me are connected in the action / dash camera business.

Fortunately i have a Sjcam SJ6 air and a SJ6 legend and a SJ7 star cameras i can tear into, but none of them support 240 FPS in 1080p only 120 on the SJ7 star, so no slow motion shots.

I am more inclined to wait for a 5G phone upgrade, and then use that as that should be able to record 1000 FPS in 1080p, for truly sweet slow motion,,,,, 240 FPS after all are not that slow with fast moving things.

That however in my case will not be before next year unless my phone break.

Even with all done on the OA camera to narrow its FOV ( Field Of View ) it will still be 100 deg wide ( i assume ) much more than the 10 - 20 degree FOV of a narrower lens.

The eagle vision cameras seem to use a 12 mm lens.

I use a 12 mm lens on my "zoom" dashcam myself, which give me small detail much further out than the regular wide angle lenses of dashcams,,,, and action cameras.

This footage is the middle 50 % of the recordings, only trimmed top and bottom, field of view to the sides have not been touched, and as you can see the 12 mm camera are much narrower FOV.

There also is a video on youtube with a guy trying to change the lens in the OA, he pretty much have to take it all apart, and then he chicken out and put it back together.

It could be other scope camera systems have a build in corrective lens,,,,, i suppose you could do that just like attaching a lens to a action camera lens to get macro filming.

Just i have not seen / noticed that, but then again i have not looked much into conventional setups, i would prefer to have a dedicated scope that can do both day and night, and record it.

I do have a DIY project lined up with a dashcam where i want to use the one lens to see thru with my DIY night vision goggle, and then have the other on the scope, so i can switch back and forth between the 2 lenses depending on what i need.

But to pull this off i need someone to modify the firmware so the camera record in B&W just like CCTV cameras do at night when aided by IR light, and then i need to procure a couple of lenses too without IR cut filters.

Thats still just 1080p / 30 FPS, but i figure night vision goggle ( a cheap set of FPV goggles from hobbyking ) and the camera on the gun would be a fun experiment,,,,, also i need to get a new dascam first as this project is going to be made with what have been my primary camera in the car for well over a year.

If the firmware dont get modified then the footage get a horrible magenta hue,,,,, been there done that.

Tis is recorded with a modified ( IR cut filter removed Toshiba camcoder on the scope )

DIY night scope camera, from years ago, this is actually a modified dashcam.

Just cameras in my apartment no scope attached, Toshiba camcorder and cheap modified dashcam.

It is paramount to use sensors with good IR / NIR abilities, and sensitive as all that glass in scope + lens block out a helluva lot of light, those old videos above, that was all bad or mediocre sensors, much better available today so you do not need a 10 W IR light.

As you can see by UL dates,,,, i been playing around for a while.
