People in these two groups have found a light leaking issue that occurs from the mount on camera. https://www.facebook.com/groups/184416535083113/

Here is a photo of the light leak. I did a simple test putting the lens cap on and shot at iso 25600 for 20 seconds in low indoor lighting.

A Person in both groups took a long real world exposure and the light leaks did affect the outcome of his photograph.

Looking at the two photos together the light leaks look like they are coming from the same points. More people have confirmed this in the groups. Also the same person that took the photo above found that the e mount is squishy. He also has seemed to have found a temporary solution

"So I am now more convinced than ever that the source of the major light leak, the crescent leak showing up on the upper right quadrant of the image, is caused by that slight gap between the silver flange and the resin substrate. To get rid of it, all I needed to do was apply a very thin strip of gaffer's tape to the gap between the silver flange and the orange ring (see pic). Note that this isn't covering the space between the orange ring and the body nor is it really providing a good shield between the flange and the rear of the lens. It's just covering the gap between the flange and the orange ring, and that takes care of the crescent light leak "

The tape idea was found on twitter http://twitpic.com/dpocow
