Does the EOS 5D Mark III have a light-leaking problem? | CanonWatch

Another demonstration of why not to be an early adopter of new camera body releases. This one will be particularly painful for affected owners as unlike defects in previous/other Canon models this likely won’t be a ‘simple’ firmware update fix. Unless you’re a first time camera owner, or are otherwise without a current body, it’s always worth waiting for the post-release bugs to be discovered and fixed before upgrading or replacing your existing gear (and not just with Canon cameras).
