Best Underwater Drone Specs - Sensor Size, Aperture, ISO, Field of View

[Eternal Angler]

So I'm starting to learn more about the sensor size, aperture, field of view and how much they matter when filming fish at my local lake. Wish I knew what I know now before buying the Geneinno Titan. Anyways, a Facebook member by the name of Avraham posted a link to Finish-Tackle.com, which gives a full breakdown of the different sensor size of each underwater drone or ROV, along with aperture, and even ISO, which I haven't even been factoring in. I guess my Titan has a really good ISO, the Fifish P3 seems to be a leader with 12,800. Also a breakdown on the maximum frames per second, crazy, I never knew that the Fifish V6 can film in 240fps, that's incredible! My Titan seems to be really lacking in this area with only 30fps... Just so much to consider when buying an underwater drone, hopefully this table graph can help!

Here's also a photo of the specs if you want to download.

Anything wider than a 2.8mm 120* fov lens on a micro cam will result in unwanted fisheye distortion.

Yeah I don't want distortion for exploring and recording fish... I mean I've captured a lot of footage with my GoPro 5 by putting it on a mushroom anchor, the fisheye wasn't too bad, but the fisheye with the T1 was very disappointing and worse than the GoPro at wideview setting, which is 170 degrees. At least with the GoPro you can change to a linear or narrow view to prevent the fisheye, which is around 90 degrees, but I couldn't change the camera angle through the Geneinno software app, sucks. Maybe they can change that in the future.

I must say, comparing the 166 degree view of the Fifish V6 to the Geneinno T1 160 degree view. There doesn't seem to be much fish eye distortion of the V6, I wonder why that is examining this video and the dock pilings? A lot more distortion I think in the Geneinno T1, yet it has a slightly less FOV.

Fifish V6 - 166 degree FOV

Geneinno T1 - 160 degrees FOV
