Summary: Honestly I wasn't going to get this due to the high price, although I spend a lot on camera gear. That was until I had to shoot Jewelry and decided to use live view on my D700. The fact that you can fine tune lighting and focus, and see it on a computer screen at the same time(I was tethered on a laptop) was extremely helpful. However, my batteries were running out of juice like crazy, I had to keep one on the charger and one in the camera all the time.
Summary: $80 is a bit much for a simple AC adapter, but anything that says Nikon on it is tripled in price. It's either buy this or wear out $40 batteries. What really gets me is having to buy two of them. I bought the model (EH6 I believe) for my D200 and then I had to buy this one when I upgraded to a D300. You would think that the 2 cameras are so similar that they would use the same voltages. But, I guess if you want to play with the big guys you have to pay the price.
Summary: I had a really hard locating this item from local vendors... everyone was out. I then found it listed on Amazon and ordered it with expidited shipping. Received it quickly and on time, and it works great with my D80 camera. I downloaded a time lapse program online to operate the camera automatically via laptop and I have run time lapse for periods longer than a week and then made them into stop-shot videos with great success.
Summary: Just pop this in the EP-5 where your battery goes, and then connect it to the EH-5A (for a D40). There's a little plug that pulls down so the cord can exit. No more cycling through batteries and worring about ruining an extended exposure with my astrophotography! Highly recomended. The product almost pays for itself when you consider the cost for 3 batteries and all the headaches!
Nikon EH-5A AC Adapter for Nikon Digital SLR Cameras
SC "N2ShoeBiz", Amazon
5 March 2009
Summary: This product work well with several Nikon models. I would highly recommend the adapter if you do a lot of stationary photography work. It takes away the cumbersome task of constantly charging and swapping out batteries.
Summary: This is a great OEM AC power supply for the camera; most useful for lengthy computer capture sessions, or studio shooting. I made the mistake of buying a D300 system over the phone from a bait and switch Brooklyn Wholesaler outfit. Their online D300 body price was great, but once I asked if it was a gray market or USA model, the cost of USA body was $300 more than the advertised D300, and all the accessories were cheap non-OEM at or above OEM prices.
