One of Nikon's next major DSLR revisions received a large, detailed leak today that hints at a major rethink of the entry-level camera. The D3100 (rumored before as the D4000) should place a heavy emphasis on video and should be one of the first Nikon DSLRs to implement continuous autofocusing: the camera will constantly adjust the focus either when recording movies or when using the live view mode. Nikon was reported by Nikon Rumors as having already reportedly confirmed that continuous AF will come to future cameras, but hasn't said when.
