D7100 has the 1,3x crop mode with 15 MPx - this is the same as m4/3, therefore you have:

300mm x 2 = 600mm without TC

300mm x 2 x 1.4 = 840 mm with TC1.4

300mm x 2 x 1.7 = 1020 mm with TC 1.7

300mm x 1.4 x 2.7 = 1134 mm with TC1.4x on "Nikon 1" body with converter with autofocus

Indeed.

I am not quite sure what to make of the crop mode on the D7100. The increased FPS and smaller file size is useful but the crop itself is just a crop. Still, at least it is 15mp+. And the lack of AA filter could/should allow a harder crop.

The Panasonic G series have a similar crop (jpeg only) when using M and S image sizes which I never found useful, partly because I usually shoot raw and partly because a distant subject is easier to frame without it followed by cropping in post.
