Yes, there would probably be an ideal range of shutter speeds, and it would take careful work to adjust the rate. if you are looking for constant blur it would have to move that distance over the span of time that the sensor is exposed. Also, it may depend on the period of time that the shutter is completely open (flash sync period), and of course it would not work with a flash. > > > -- > > William Robb > > -- > 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. -- Larry Colen l...@red4est.com sent from i4est -- 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.
