Olympus m.zuiko 14-150mm F/4.0-5.6 m4/3 lens. I just switched back to Panasonic and need one with IS built in. I'll either trade + money for your Panasonic 14-140mm or sell outright. The lens is barely used and boxed. Price is $479.00 shipped PP USA only. I also have an Olympus FL-36 (not R) flash which is great with this lens. It's $100. no box or instructions but is pristine and has the pouch.
