The two-piece battery grip is a very good addition to the E-M5 for vertical shooting. The handle is well balanced and easy to install. Unlike competitors, he does not intervene in the battery compartment of the housing. Instead, the power of the batteries is transmitted through sealed contacts on housing. This means that both components are mounted quickly and just as quickly away again. Processing acts Reassuringly solid. Against accidental operation helps a lock toggle to the additional keys can be temporarily disabled. To my mind could handle the extension, be a little higher. The depth is perfect, but in the OM-D I do not have more the height (the little finger reaches into space) than the depth.
5 stars I can not forgive, unfortunately, because the handle does not allow the use of AA batteries or batteries. Although it has more capacity without battery change, but given the delays by the model BLN-1 (as of mid-2012), it is of little.
