Tecno unveils Eagle Eye Lens - the first dual prism tele camera that automatically tracks objects

Typical telephoto cameras have Optical Image Stabilization (OIS) because optical magnification also multiplies handshake. This works well for static objects, but you still have to track moving objects manually – and that tends to amplify handshake. Tecno now claims to have come up with a solution, a system of two prism instead of one (it’s the first of its kind). Each prism can rotate along one axis – one can do +/-8°, the other +/-10°. With the two prisms combined the camera is able to automatically track an object – by as much as +/-16° on one axis and +/-20° on the other, according to...
