Olympus has announced a firmware update for its new Pen camera that will allow the device to operate more effectively with the following MFT lenses from Panasonic:
-Panasonic LUMIX G VARIO 14-140mm f/4.0-5.8
-Panasonic LUMIX G VARIO 14-45mm f/3.5-5.6
The firmware update for Panasonic’s 14-140mm MFT “superzoom” increases overall performance stability between body and lens.
Similarly, the 14-45mm firmware update improves auto focus performance for still and movie recording, improves the stability of optical image stabilization during movie recording and decreases audible noise while adjusting the aperture while movie recording.
