Help with finding the right camera!


New member
I am conducting research on octopus in a lab at my school and am curious about what the optimal camera specs are for filming of this nature. If the camera is waterproof and mounted at the top of the tank what lens size would be appropriate to capture video the tank? I am thinking of using a 360 degree 12MP/4K camera (12 fps) with a 2.1 mm fixed lens. I am under the impression that cameras usually lose their clarity as the field of view increases so I am wondering if a 2.1 mm lens might be too small or if it is a good size since objects within the tank are relatively close to the camera.
