The 14.2-megapixel Nikon D3100 is a great entry-level digital SLR, and at $699.95 (list, with 18-55mm lens) it's the least-expensive D-SLR to capture 1080p video. It also includes a feature no other D-SLR has, continuous autofocus during video recording, which makes the D3100 feel like a camcorder while it's shooting. The camera can detect faces, lock on, and adjust the focus automatically to make video capture even easier. The only problem is that the lens isn't silent, so every time it refocuses you'll hear it. The Sony Alpha55 SLT-A55VL has faster autofocus, and the Sony NEX-3 and the Panasonic Lumix GH1 can focus silently, but if you want continuous autofocus in a true D-SLR, plus a true optical viewfinder, the Nikon D3100 is your only choice-but it's a good one.
