Mark! Apologies for taking that out of context. :-) > That I'm generally best optimizing the aperture for the picture, and not > trying to optimize the aperture for MTF. Yes!! One of the best arguments for keeping one lens on your camera for a goodly time and really learning it, is so you can empirically determine your own personal subject-lens-camera-brain sweet spots. For example I've learned that f/2.0 on the DA*55 is a really sweet spot for beautiful portraits. I have never once pored over any MTF * charts for any Pentax lens, let alone the DA*55. But I've taken thousands of frames with it and analyzed and post-processed them until they hit my sweet spot for beauty. -- -bmw [*] or MTBF, or BMF -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
