I want to use manual flash power settings in combination with trailing sync with older manual non-smc (m42) lenses on a Pentax K-7.
This is for extreme macro and focus stacking. I'm using microscope lenses and adapters, hence it's M42 mount, with no electronic connection. I need trailing flash because I mix ambient and flash but need to eliminate flash ghosting. I believe only Metz 58 AF-1 or 48 AF-1 models will work? I have found out that I can actually get a trailing pop with a Pentax AF360FGZ flash mounted, but because the lens is non-A, it will only do 100% flash power every pop, which is no good for me because the flash won't last several hundred shots.
Can anyone confirm that the Metz 58 will let you set the power output on a Pentax trailing sync shot using non-a lenses?
