Of my few, but significant complaints about the E-M1 are battery life and ergonomics (even though vastly improved over the E-M5). When the hld-7 is attached it transforms the E-M1 into a fantast handling camera and shoot all day without concern to battery life. Cheers to Olympus for addressing these issues inherent to the M43 system. Love my E-M1 and love it more with the battery grip attached. I'm an Olypus user for life!

When I first used the HLD-7 grip, it drained the batteries quickly while it sat on the shelf. I found a few others had the same experience and we compensated by only using the grip battery and leaving out when not in use. Now, it appears that the problem has been solved. I can leave both batteries in for several days without it running the camera down to nothing. Huge relief.
The grip itself is extremely useful. My pro work lives in big and fast FT glass and that grip just makes the older (but still incredible) lenses practical to use. You also gain programmable buttons for frequently used functions and a port for the AC adapter when you need to run the camera all day. Put it all together, and the E-M1 is a true transformer camera. Strip it down to just the body and standard MFT glass for when you need to travel. Bulk it up with the HLD-7 and FT glass and it looks like any other pro DSLR. My only wish (for 4 vs 5 stars) is that they had found a way to button another button at the other end. There are times when it's just easier to shoot by flipping the camera in the other vertical direction. My prior FT Oly had that on a third party grip and I really do miss that 2nd button.

I have the HLD-7 on both of my E-M1 bodies and they are great! Balances the camera and allows for shooting a complete sporting event without missing a shot. if you set the camera up using the PHB battery first then you can swap the battery out with out detaching the grip from the camera and never miss a shot. Neither of mine exhibit the battery draining issue. I leave them attached 100% of the time and have never had them drain my batteries, my cameras are always ready to go. A definite must have accessory for the E-M1.

The review that says "it drains both batteries unless disconnected" is absolutely wrong. I use this thing all the time, almost never detach, and it just does not do what that person says, so, don't let that review bother you... I'm not saying his isn't doing it but if it is there is a service issue.

The HLD-7 grip is a good value and helps make the body easier to use for vertical/portrait orientation. It is full featured and features solid construction. Perhaps the biggest advantage is the extra battery that it will take, doubling the amount of shooting possible. The camera switches automatically from the depleted battery to the fresh one. I have not experienced the issue the first reviewer has had. To me, this grip makes an already excellent camera, feel even more like it professional camera it is.

This grip is essential for four thirds glass and pretty valuable for doing portrait work. I use it constantly. But leave it attached to the body and it will drain both the grip and body battery within a day or so. Leave it off and the body battery will last for much longer. There is no off switch that will stop or limit this behavior. Somehow in the rush to get a great camera out, this helpful accessory was botched.

I bought the battery grip immediately since I have quite a few 4/3 lenses; it helps balance out the camera when using them. It's also a big help when using the intervalometer mode on the camera by supplying extra power when shooting hundreds of still photos. Definitely worth the $200!
