Preflash based TTL is inherently less accurate than TTL-OTF flash since the latter measures the light during the exposure. However preflash based systems are also fooled in less situations, so accuracy is to some extent a wash. -Adam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
