Just trying out my new macro accessories, the Raynox 150 and Viltrox JY-670 Macro Ring Flash.
The ring flash is manual only and doesn't fire continuously on the K5, that is, it fires once and then doesn't fire again. I read a thread here that said the only way to make it fire again was to turn it off and on, but I did find another work-around. Pressing the Pilot light button on the flash sets it to fire again. Far less tedious than switching it on and off between shots, especially when focus stacking. I think I am going to enjoy this new macro set up
