But there's a tradeoff, as pixel density contributes to noise. The K-5 sensor is still one of the most highly rated in the camera biz. I wouldn't trade low-noise at high ISO for more detail. Perhaps others would, but the K-5 works well for me as is. > > Tom C. > > -- > PDML Pentax-Discuss Mail List > [email protected] > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
