Not long ago I was in the middle of a photo shoot and realized I my battery was almost dead. I was able to finish, but it made me realize I need more batteries. While researching batteries, I found that for not much more, I could buy an entire battery grip. So that is the route I went.
There are myriads of Chinese made battery grips out there. What I wanted was one that would use multiple Nikon batteries for extended power, but also be able to take AA batteries in a pinch. The one I selected was the NIKD40. I purchased it off of eBay. As to the manufacture, I have no idea who it would be. A lot of equipment comes from China nowadays unbranded.
The first thing I noticed that it was huge! This actually is not a problem because I found out that most battery grips are about the same size.
You can place two Nikon Batteries in the cartridge for double the battery life, or it will still take just a single battery and work fine.
You can also load six AA batteries in the other cartridge to power the camera. This is a great feature, because in a pinch, you can get AA batteries anywhere. If you can’t find a place to charge your batteries, you can still keep shooting.
I was very curious as to how this worked. It’s pretty ingenious, if y0u ask me. It utilizes the cameras infrared remote shutter capabilities by adding a pop out IR transmitter and a release button on the battery grip. When you set your camera to use a remote shutter release, the IR transmitter on the grip is triggered by the vertical button and sends a signal to the camera to take the photo.
This also means that if you put the stock battery door back on, you can actually use the grip as a remote shutter release without spending the extra money to get the official one from Nikon. I tested it, and it really works!
This is a cool gadget that really works!
It fits the Nikon D40, D40X, D60, and D3000 DSLR cameras
