- D5100 although has less Mega pixel (but it almost means nothing these days unless you want to make print has large as a 2 story apartment), D5100 can handle better in low light, has higher ISO.
- D5100 has more auto focus points, which is extremely important to getting accurate shots (inaccurate AF means fuzzy/unusable photo). Unless you only shoot from tripods with manual modes, then this won't matter much.- An ever so slightly bigger sensor in D5100 vs D3200 really means nothing. Good image quality is the result of your lenses. Your lenses will likely to make all the differences, camera bodies will determine AF accuracy, format (full or cropped, but both cameras here are cropped), and all the nifty modes/electronics to help make your life easier.If I were you, I would go to D5100, because the articulate screen sometimes really help a lot, and it has more features and options as D3200 is marketed more toward a point and shoot type users. But the final decision is yours. Keep in mind that a good photographer would shoot with D3200 with quality as good as a Leica if he knows what he is doing (and what lenses he is using).
