Actually, there is one major reason that 24x36 dominates the larger sensor market. Lens availability. Since that is the traditional 35mm frame size, there's a far larger selection of lenses available than for larger sensor sizes which require use of a Medium Format mount. -Adam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
