Nex-7 battery grip
I learned about the Ownsuer Battery Grip on this forum. I just took delivery of it today. It is easy to attach to the Nex-7, and it added about 0.5 kg to the wieght of my camera. The ergonomics of the grip are good and it allows me to handle my camera without difficulty. Its made out of plastic but it feels sturdy. The cost was $124.95 which included delivery from Hong Kong. I ordered it 11/21/12 and it arrived 11/26/12. I bought it from a company Harvest One LTD out of Hong Kong.
