12x Optical Zoom and a Brightness of F2.8 to 3.3 The LEICA DC VARIO-ELMARIT lens is a small, lightweight lens that packs the same zoom power as a big, clunky 400mm-class film camera lens. This 12x optical zoom lens is super-bright too, at F2.8 to 3.3 with a focal length of 6 to 72mm (equivalent to 35mm to 420mm in a 35mm film camera). You’ve got all the power and flexibility you need to take exquisitely beautiful shots all the way from telephoto to wide angle and macro. The DMC-FZ4 also has a 4x digital zoom. Use it together with the 12x optical zoom and you’ve got ultra-powerful 48x zooming1 – roughly equivalent to a huge 1680mm lens on a 35mm camera. Our MEGA Optical Image Stabilizer Helps Eliminate Blurry Pictures Jitter from shaky hands is one of the main reasons why cameras produce blurry images. We don’t expect everyone to have hands of stone when taking pictures–that’s why Lumix cameras help solve the problem of unsteady hands with advanced MEGA Optical Image Stabilizer technology. The DMC-FZ4 has a built-in gyrosensor that detects any hand movement and relays a signal to a tiny microcomputer inside the camera, which instantly calculates the compensation needed. A linear motor then shifts the Optical Image Stabilizer lens as necessary to guide incoming light from the image straight to the CCD. You won’t even notice it working-all you’ll see are the outstanding results!
