Reports online suggest that the light leak originates from the lens mount.
In a statement, Sony told Amateur Photographer: ‘We are aware of reports of light leakage on the ILCE-7 and the ILCE-7R.
‘This issue does not affect any photographs taken in normal photographic conditions.
‘However, we are currently investigating the concerns that have been raised.’
The full-frame compact system cameras were first unveiled in October 2013.
