Re: Macro the 1/f rule and flash duration

Very interesting. I am surprised that the minimum duration is only 1/3000 sec. I'll take your word for the maths (or math as you would say). I haven't got my mathermatical head on at the moment. I think with freezing motion it is not one of those dichotomies where it is sharp or not type things. It is probably more degrees of sharpness. Actually the figures you come up with suggest a lot of photos with the MPE and flash at high magnification are in an area where motion blur could but will not always effect sharpness.
