The TM15 features a 16x optical zoom. You can zoom close to catch dynamic shots of distant objects. And because the zoom is optical, there's limited image degradation. Also, Panasonic's advanced O.I.S. helps prevent blurring - typically a big concern when shooting with a zoom. This combination of optical zoom and advanced O.I.S. gives you the ability to take fantastic zoom shots.Panasonic's advanced O.I.S. helps suppress the effects of hand-shake as you shoot, for both motion and still images. This system uses gyro sensors to detect even tiny amounts of hand-shake, then shifts a lens and adjusts the optical axis to compensate - all at an astounding 4,000 times per second. The O.I.S. corrective lens shifts and stabilizes the image the instant that the shutter button is pressed, to enable greater precision in stabilization. You get all the beauty and minimal blurring.There's nothing more disappointing than shooting a once-in-a-lifetime event on video, only to discover that the images are blurry or poorly exposed because of backlighting. Panasonic's iA helps avoid problems in difficult shooting situations by automatically making the optimal camera settings and activating certain functions. For example, iA includes AF tracking, a function that "locks" on and follows a subject as it moves, so images are sharply focused and properly exposed. This technology is a huge help for everyone.
