The HLD-7 is designed for owners of E-M1 actually a no-brainer, because the camera is through the handle again significantly better in the hand. In particular, if you use larger lenses such as. The 40-150mm f2.8 PRO M.Zuiko or older Four Thirds lenses makes the handle by the significantly improved ergonomics positive impact. In addition, the possibility to use a second battery is also very useful battery life is at the mirrorless system cameras yes generally much shorter than in a DSLR.
Why I forgive then "only" 4 stars?
On the one hand I find it very unfortunate that Olympus with a battery grip of at least an MSRP of 229, - Euro has used as the material plastic. For the price I expect actually that the handle is made of the same magnesium alloy is produced as the camera itself. Admittedly, it is high-quality plastic, yet I find it sad.
Another point of bothers me is that the battery grip even no button / control nipple is attached to at photos in portrait format such as. Portraits to move the focus point. So you have to specify the focal point previously coarsely and then pivot. That goes with the MB-D14 battery grip I just use my Nikon to better.
