John, ~any~ serious photographer, and I'd include the entire PDML list, knows you're correct. That being something we might agree on, the human brain and a little experience calculates all your given parameters in milliseconds and makes the decisions you (we) need to make the photo. Shotgunners, bowlers and other endeavors which demand hand-eye coordination and instinctive targeting call it "follow through." > Panning using slow flash sync is not much help if multiple subjects > are moving in different directions, or, if one does not know in > advance that the subject(s) are going to move, or, heaven forbid, if > one does not want to blur the background." Again you're correct, given your conditions. But I say the "experienced" shooter, knowing who and what s/he wants to be or ~is~ the main subject, will ~not~ be confused by all the extemporaneous movement. > "Slow flash sync is best for static or very slowly moving objects. > Panning could help keep a portion of the frame in focus under certain > circumstances." > > "A more reliable and permanent solution to image blur caused by slow > flash sync is a faster flash sync rate." But... but slow sync is most often ~only~ used on static subjects, the main reason for using the technique being to allow for ambient exposures. But panning is a learned technique which every competent shooter should practice. ***We know that (most) PENTAX cameras, with the exception of the PZ class, all four of whom have 1/250th flash sync, have flash syncs of 1/125th or slower. ****As I remember, high speed flash sync was instituted by and for the "pro" camera genre even before the advent of ISO 400, 640 and 800 speed films, the combination of which, with fast, f/2.8 or better "pro" lenses, did not easily accommodate outdoor "slow" sync. Fast lenses and fast film forces the shooter to close down their apertures, sometimes to f/22 or smaller, meaning getting "bokeh" in a shot impossible, especially for wildlife. ****LX owners often decry their atrociously slow LX flash sync, but for different reasons. > > -- > Mafud [EMAIL PROTECTED] [EMAIL PROTECTED] - This message is from the Pentax-Discuss Mail List.
