I'm looking to upgrade from my Coolpix P100 to either the D3100 or the D5100. I'm leaning heavily towards the D5100, because it has more of the options I'm looking for, as well as the articulating screen similar to my P100's. My main concern is that, in doing my research on the D5100, I've seen some reviews that were negative. Every negative review I read was regarding the software issue that affects the memory cards or the issue with the blacked out photos that resulted in the camera having to go back. It seemed like there would be 1 negative review for every 10 positive. What worries me is how many of those that posted positive reviews ended up having either one or both of those issues and didn't update their reviews to reflect it? I understand with anything electronic, it can sometimes be a game of chance - either you get lucky and have no issues, or you get a lemon. There's no way to predict by looking at the item itself, or even by basing your decision solely on reviews. I guess what I'm wondering is...has anyone here on this forum experienced either issue, and how long have you had your D5100's? Would you recommend it? I'm an amateur, but a pro amateur, if there is such a thing, and I'm ready to take the step up to a camera of this caliber. My only concern is the reliability of the camera. Thank you so much for reading such a long winded post and I hope everyone has a nice day!
