You'd need a full-frame camera whose pixel pitch equaled that of the APS-C camera. Then, yes. But my D700, cropped to APS-C, is 5MP, whereas my D200 was 10MP. The equal pixel pitch doesn't exist between very many pairs of FF vs. APS-C cameras. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
