Last time I was looking at A/Ds (some time ago), converters with a higher bit-depth were far more linear than those with lower bit- depth, across that lower bit-depth. For example, a 22-bit A/D would be more linear across 12 bits than a 12-bit A/D would be. Is that going to be the case here? I know that non-linearity can be corrected in software, but nothing's ever as good as having decent raw data to start with. - Dave -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
