The Nikon D2X is 12MP on an APS sensor and the Sony is 10MP on a smaller-than-APS sensor. And actually I have not heard of poor noise performance with the D2X(s), on the contrary, I've heard people praise it. -- Christian http://photography.skofteland.net -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
