The world's first interchangeable 3D lens Lumix G 12.5mm/F12 (H-FT012) realizes 3D shooting. It features two optical systems installed within the diameter of the lens mount, creating stereo images from the left and right lenses, to be processed with a 3D image processing system. Despite its unique performance, the 3D lens keeps its size extremely compact thanks to Panasonic's advanced optical technologies and consideration of image processing system as well as structural design.Shooting 3D content with an interchangeable lens system camera was possible by using panorama systems or a combination of two lenses and two CCDs, but these systems have drawbacks including the need for a dedicated 3D camera and the difficulties capturing moving objects. However, this compact 3D-capable interchangeable lens allows easier handling and instant 3D shooting with cameras without a special structure for 3D shooting. It produces 3D images without distortion or time lag between left and right images, even for moving objects. The 3D images, even close-up shots, taken with this lens are easy on the eyes when viewed on 3D VIERA televisions.
