You forgot the serious tag <| sep |> This reminds me of the people that used to defect from Russia and other Warsaw Pact countries during the Cold War . <| sep |> I ' ve seen some decent stuff out of a GoPro . I recommended both of those because they ' re the goto options for 4 K the A 6300 is a bit flawed , but the A 6500 appears to fix it , and Sony ' s APSC camcorders are the stuff of major motion pictures . More pixels means more stabilization . One option is the Panasonic G 7 at about $ 500 with lens it ' s a bit big and you ' d need an enclosure , but it ' s cheap and works rather well . The $ 500 ZCamera E 1 ' s video bitrate sucks , but it ' s tiny barely bigger than a GoPro and 4 K and will give you better video than a GoPro . if you add a solid lens . Finally , there ' s Sony ' s RX 100 MKIV and MKV , which do 4 k . Lots of underwater enclosures , too . Not cheap , though , and not hugely wide they zoom .
