I have a brand new XE1 and an 18-55. I did a bunch of testing with the 35/1.4. No issues. But, when I attached the 18-55, the camera won't function. The image comes on for a brief second, then all is black. There is a very, very slight pulsing of light on the LCD, but I cannot trigger the shutter or even turn on the menu. I've tried remounting the lens several times and also cleaning the contacts. I even tried setting the camera to "shoot without lens" to on. Nothing. It seems to me to be defective, but I thought I'd ask if anyone had any similar experience, or might know a solution.
