    The Olympus M. Zuiko Digital ED 12-40mm f/2.8 PRO Lens is getting rave reviews from users and professional reviewers alike. However, following a report by one of our members that the mount broke off of his 12-40 with very little impact, three additional owners have posted in our forum to report similar fates for their new 12-40mm lens. In each case, the damage was says to have occurred with little to no impact.

    Such reports aren't unique to this lens. For example, a Google search for "Nikon 24-70 mount broken" turns up a number of similar stories of mounts breaking off with little to no cause. Still, the four reports in our forums of Olympus 12-40 mount breakage, three of which are accompanied by photos, raise the possibility of a manufacturing issue with this new lens.

    I've notified our contacts at Olympus of these reports and will post an update if they provide any additional information. I'm confident that if their investigation confirms that an issue is present, they will take the appropriate steps to address it as they did with the bezel crack issue on the OM-D E-M5 (also first identified and discussed in our forum).

    Here are the posts from users reporting this issue in our forums to date:
