Lens "H-FS14140" is very suitable for my universal "Photo & Film" Supplies to my DMC GF6. The discreet operating noise of the lens I stopped first for a defect until I got the following to read from Panasonic: When optical image stabilizer (OIS) Panasonic is a small lens horizontally by a magnetic field in the lens. The control is based on two gyro sensors (horizontal and vertical). A certain amount of noise is in this case normal operation. In normal shooting condition but these sounds should take a back seat. Addendum Feb. 2015: In the long term (about 1 year) I was not satisfied with dieem lens on my GX7 because I received reliable sharpness only with the electronic shutter. Have given it to "Olympus Digital ED 14-150mm M.Zuiko" in payment. With the Olympus I get now finally also with the normal closure reliable sharpness in all focal areas.
