It is a brand new, never used lens that came with camera. As far as I have 14-140mm lens I am not going to use this one. The lens is compatible with any Micro four thirds Panasonic and Olympus cameras. The LUMIX G VARIO 45-150 mm / F4.0-5.6 ASPH. / MEGA O.I.S. (H-FS45150) lens is compatible with Compact System Cameras (DSLM) LUMIX G models that comply with Micro Four Thirds System standard. Highly Compact And Lightweight Featuring an ultra-compact size and light weight body, the LUMIX G VARIO 45-150 mm / F4.0-5.6 ASPH. / MEGA O.I.S. lens offers a versatile zoom range of 45-150 mm (35 mm camera equivalent: 90-300 mm) providing a versatile medium zoom range for daily situations. Stabilized Near Silent Focusing For Video And Still The LUMIX G VARIO 45-150 mm / F4.0-5.6 ASPH. / MEGA O.I.S. lens incorporates Panasonic's MEGA O.I.S. (Optical Image Stabilizer), which makes it easy to shoot super clear shots even in low-lit situations by suppressing the blur caused by a hand movement. The lens' inner focus system enables excellent resolution and contrast from full life-size magnification to infinity and the inclusion of a stepping motor makes focusing action smooth and near silent for use in both video and photo recording. When used with the LUMIX G Micro System line, users can also take advantage of the high-speed, high-precision Contract AF (Auto Focus) System.
