The camera is about 45 days old. When it was just out of the box, I noticed that sometimes the menu would unexpectedly close when I was changing something. Didn't happen often. Then, one day I got the ERR message; cured that by releasing the shutter a couple of times per the user manual; another time, three photos in a row were overexposed while using aperture priority...not just the background, but everything in them...subject, background, all. I assumed it was user error somehow, and perhaps it was. On a different day, I noticed that after changing from M to A that the meter on the bottom of the viewfinder was still there, as though I were still in M mode, but moving the control wheel for the shutter didn't change it, but moving the aperture control did change aperture values. I turned the camera off, then on and that seemed to fix it. Then, last night I performed a firmware update. I've done these a few times on the other camera I had with no problems, and I followed the directions here the same as always; format the card, put the bin file into the directory root, don't run off camera until told to do so, etc. But the camera told me there wasn't enough battery charge to perform the update. The battery was at 57%. Ok, so I selected NO to the upgrade, turned off the camera, swapped batteries, then then ran the update again. This time, all seemed normal, but when I accessed the menu to format the card again, the camera froze. No buttons worked - couldn't turn it off, even - and I eventually removed the battery. Then I double checked the battery insertion, swapped out the SD cards (because I noticed the green light indicating installation of a card hadn't come on) and this time the LCD had white rectangular boxes throughout the display. Rinse and repeat - next try had garbled letters on LCD, then freezing; next try had normal operation for about 3 minutes, then froze; next try had a pink and blue LCD, then froze. So, anyway, any ideas about what might have caused this? The update? Anyone experienced anything similar? The camera is currently on its way to Nikon repair, I'm just hoping there will be a positive fix and not a run around. I'm a little concerned that Nikon's warranty info said that the warranty does not cover software issues. Is firmware = software? Just wanted to share some angst.
