Originally posted by Canada_Rockies I read the link to the article - thanks for that! I do wonder about the emphasis on manual exposure, though. My macro lens is the M 100/4, so I would be in manual because that is the only way I can get the lens stopped down for the exposure. I am thinking however, that TAv might be a better way to go, with a slight (-0.7 EV) offset for the lens exposure. I can try the technique with the DA 55-300 at closest distance and see if it works. This won't be true macro, but should be good enough with the K3, combined with cropping, to get butterflies and the like, or my favourite nemesis, dragonflies. It is too late for the season here, but I can certainly check out the exposures on static subjects.
I think the emphasis on manual exposure because the idea is to set your sync speed to max (1/180 s), to your desired aperture (i usually use f16-f20), and base ISO...then vary the flash power to expose your subject.
