A "must" for the E-M5

I have for some days the HLD-6 in use. My Vorrezendent wrote everything at some length to the battery grip is finally available. The first stage gives the E-M5 a better grip, the second stage increases with battery installed, the possible useful life. Through this clever modular system is Olympus succeeded in that the user can customize their E-M5 individually. Remain the dust + splash protection received and so the camera can continue to be used under adverse weather conditions. The only complaint is the rather high price. The quality and workmanship are but class.
