The recently announced Octopus Cinema Camera with a modular sensor, mount, and other components could, in theory, become a customizable professional solution slow motion camera that is unencumbered by firm specs but by a fluid and upgradeable sensor and component path. The Axiom camera is also something akin to this but has yet to ship. The Octopus has in prototype form been fitted with a 4/3 sensor capable of up to 240fps in 2k RAW and a full-frame that allows 3k up to 100fps.
The body looks eerily similar to Phantom cameras with the white machined exterior with fans and ports protruding the body. While 240fps at 2k is not what we could call really professional slow motion, it is based on an open architecture in hardware and software that could window the sensor down and possibly offer more frame rates at 1080p and 720p for maybe a 480fps RAW capture in HD.
