Roger Cicala from Lensrentals tested how sever the A7r light leak issue is and these are his findings:

  • We tested several A7rs and several A7s and all were the same, so it’s simply a design issue, not a batch of defective cameras.
  • The light leak occurs with the body cap in place, but is more severe with a 35 f/2.8 Sony lens mounted instead of the body cap.
  • The leak is worst when the light is shined onto the lens-release button area. It is also bad when the light shines onto the lower left quadrant of the lens mount, and directly above the lens mount. Other areas either didn’t leak or showed only a thin line that was far less pronounced than these areas.
  • Wrapping something around the lens mount stopped the left side leaks, but not the leaks around the lens-release button.

Roger fixed it by putting some rubbed material around the mount and lens release button. This helped to get rid of the problem. And he also wrote this:

And for you Fanboys who just can’t wait to Sony bash over this odd little issue, let he whose camera is without light leak cast the first stone. Because, so far the same problem has been found with Canon, Nikon, and Fuji cameras. I assume a similar solution will work just fine for those, too.
