| Not really correct, The D40 was not upgraded to the D60, D80 then D90.
With Canon and Nikon, there number system does not work that way. In fact the D80 was out before the D40, D60, and D90.
The D60 came out to be an upgrade to the D40, the D90 is the camera to replace and upgrade the D80.
The D3000 is a series pretty much in between the D40/D60 and the D90. |
