Keystone K-12 is your key to making home movies as easy as taking snapshots. Keystone K-12 is easy to load and features a unique "direct-through-the-lens" viewfinder that lets you see exactly what your lens sees, eliminating guesswork. Keystone K-12 has a built-in "Electric Eye" that automatically adjusts to all light conditions, indoor and out, and automatically controls the power zoom lens, which smoothly zooms from wide angle to telephoto for dramatic close-ups and sweeping long shots.
