I want to know is there any camcorder(s) that has video quality that of Nikon D3100. Nikon D3100 has maximum possible video clarity but it has time limit! (10min only )
The Nikon D3100 is intended for digital pictures; not for shooting video. The video feature is for emergency use.
If you want the sharpness, clarity, and resolution of the output from Nikon D3100, and a longer recording time, consider a professional video camera (not camcorder).
