This answer is for those few, who are aspiring to understand the question and the answer.
There are a few cameras supporting DNG native, i.e. the camera can create a DNG file as raw output. These are some Pentax, some Leica, some Hasselblad, what else?
For the probable case that the OP's question was which cameras are supported by the Adobe DNG converter, well, I would not like to get into a Wiki vs. garbage discussion here, but I personally would consult the authentic source of this information, namely: http://www.adobe.com/products/photoshop/cameraraw.html
The Sinar "eSprit 65" back creates DNG's
And I know of some Hasselblad/Imcaon backs which are listed as supported by Lightroom.
