In this video I compare the Nikon D3200 vs Nikon D3100 including image / picture quality with the 14 megapixel D3100 vs the 24 megapixel D3200, video mode including manual video and audio adjustments, 1080p video demo samples from both cameras, ISO / low light performance, screen, ergonomics, autofocus, optical viewfinder, ports including HDMI, 3.5mm microphone input, optional Wi-Fi capability with the Wu-1A adapter and whether the $150 price difference makes the D3200 a better camera over the D3100.
