For the past few years, the practice of hacking a camera’s firmware in order to increase the feature-set of said camera has been commonplace and quite popular, especially in the case of the original GH2 hack and, of course, Magic Lantern with Canon DSLRs. However, up to this point, we haven’t really seen or heard about folks hacking higher-end cameras in order to increase performance. Until now, that is. Paul Ream, a working cinematographer, recently figured out how to hack the Sony F5 so that it enables the camera to shoot 4K internally, a task which significantly closes the performance gap between the F5 and its much more expensive big brother, the F55. Furthermore, this hack raises some interesting questions about the ethics of companies limiting the functionality of their products in superficial ways.
