Want to see the inner workings of a Sony E-mount lens? Engineer Dave Jones of EEVblog was having problems with his $350 Sony 16-50mm f/3.5-5.6 OSS E-mount lens, so he decided to take it apart on camera to see what's inside. You can watch the teardown in the 26-minute video above.
Want to see what "bridge" cameras were like before the days of digital? EEVBlog got its hands on a Chinon Genesis II 35mm from 1989 and recorded the 18-minute teardown above to show us the guts.
