Light leaks in the Sony α7 and the Fujifilm X-T1

In recent days, light leaks have been detected in the Sony α7 and α7r, as well as the Fujifilm X-T1. Cameras must be hermetically sealed to prevent light from leaking. Otherwise, it will appear in our photos, especially when taking pictures with long exposures. In the case of the Sony cameras, users have found that these leaks occur because of a small hole at the camera mount.

When taking pictures with them, light appears in the upper right part of the image. Sony has acknowledged this problem and has said that their team is already working on ways to solve it. They will make public any solution they come up with. Being a hardware problem, the solution will likely be sending the camera to them.

However, users of the Sony α7 and α7r are already taking their own measures to solve these leaks. The simplest way is simply placing a rubber band where the small hole is.

For the Fujifilm X-T1, the rumor of a light leak started at the website Fuji Rumors. The light apparently leaks through ports in the camera, in particular through the audio port and HDMI port. There light leaks are most evident when long exposures are made.

Although in this case the problem is less severe, since it only occurs when one of the lids of a port has been opened because and there has to be a direct and powerful source of light, Fujifilm has been quick to announce that the camera of everyone who returns it within ten days will be repaired.

This is not the first time that an advanced camera has problems with light leaks. The guys at Image Resource have done tests and even cameras like the Nikon D800E or the Canon EOS 5D Mark III’s suffer from this. Te problem will be noticeable only when taking pictures under very specific circumstances.
