Summary: For the first 5-6 months, my 820 did fine with 2700mAh NiMH batteries. Suddenly, upon turn on, the empty battery icon flashes and it shuts down within 5 seconds. I am using the same batteries and even bought new ones. No deal. Sent it back to Fuji for repair. They sent it back with the same problem. It's a great camera otherwise. Lots of features and video w/sound. But now it just doesn't stay on long enough to use it.
Summary: i bought this camera in July and was immediately impressed. Now its 5 months later and it is starting to act up. The auto focus has become unpredictable and when you power up and down the camera is making a "mechanical" noise that is making me worried that one day it wont power up at all. I really thought this would be my last camera for a while but it seems that I'm back to shopping again.
Summary: The Finepix A820 I had took poor pictures, I was very dissapointed with this product. Maybe the unit I had was defective, your results may be better. I found that the auto focus was poor, in lower light conditions the auto focus was worthless. Pictures were not sharp despite the 8MP resolution, I feel that the Nikon 3200 (3MP) camera I have takes sharper pictures. I rarely return items, but this one went back ASAP.
